Westerhof Departments of Physiology and Pulmonary Diseases, Institute for Cardiovascular Research (ICaR-VU), VU University Medical Center, Amsterdam, the Netherlands Physiology is a branch of biology dealing with the functions and vital processes of living organisms, their parts and organs. In the later years of the Renaissance the dissection of human corpses, although still not permitted, became possible (Michelangelo, 1475–1564). The start of human anatomy can be considered to be the work of Andreas Vesalius, De humani corporis fabrica, (1543), the same year that Nikolaus Copernicus published his book on the revolution of the planets around the sun. The start of physiology is commonly considered to be in 1628, with the publication of Harvey’s (1578–1657) book: Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus (An anatomical exercise on the motion of the heart and blood in living beings). This book became almost immediately known to the Dutch medical scientists. In other words, physiology in the Netherlands started soon after 1628, thus first half of the 17th century. I will give a short description of what may be called the first ‘Golden age of physiology’ in the Netherlands. This period is followed by one age of ‘consolidation’. Then I will present a rather detailed description of the ‘Second golden age of physiology’. I will end with giving my views on present day physiology and its future. Thus, I will divide this review in the following sections (Fig. 1): 1628–1750 (‘Golden age of physiology’) 1750–1850 (‘Consolidation’) 1850–1975 (‘Second golden age of physiology’) 1975–present (‘Loss of Identity?’) • • • Golden age of physiology 1630–1750 Very soon after the appearance of Harvey’s book, Dutch physiology started to blossom. The most important researchers in what we can now consider physiology deserve a short discussion. I will use the term physiologist loosely. In Figure 2 the most important physiologists of the period are depicted. • Franz dele Boë (Franciscus Sylvius), was born in Hanau, now Germany, 15 March 1614 and died in Leiden 19 November 1672. He was a Dutch medical doctor, and professor at Leiden, as well as a scientist • (chemist, physiologist and anatomist). He was also an early supporter of R. Descartes, J.B. van Helmont and especially William Harvey. He understood Harvey’s work and theory well, and brought the concept of circulation of blood to the Netherlands. Sylvius was mentor of Johannes Walaeus, Niels Stensen, Jan Swammerdam and Reinier de Graaf. Jan de Wale (Johannes Walaeus, Koudekerke, Walcheren, 1604–Leiden, 1649), studied philosophy and medicine in Leiden and later became professor at Leiden. He first objected to Harvey’s theory, but Sylvius convinced him of its correctness. Walaeus is considered the founder of Dutch experimental physiology. He performed the so-called venous occlusion experiment to give support of the concept that blood returns to the heart, as part proof of the circulation. Niels Stensen (Nicolaus Steno, Kopenhagen, 10 January 1638–Schwerin, 26 November 1686), was anatomist and physiologist and a student of Sylvius. He discovered the lymphatic system, and proposed that the heart is an ‘ordinary’ muscle. He worked for a considerable time in the Netherlands and had contacts with the other physiologists, especially Jan Swammerdam. Although born form Lutheran parents, he later converted to the Roman-Catholic faith, and could therefore not be promoted to professor. He left the Netherlands and became Bishop in Germany (Kooijmans 2007). Jan Swammerdam (Amsterdam, 12 February 1637– Amsterdam, 17 February 1680) observed at an early age that muscle volume remained constant during a shortening contraction. He promoted the possibilities of the microscope consisting of two lenses, and was the first to report on the function of red blood cells. He wrote a book on the respiration (Respiratione, 1667) and a book on insects that was re-published in 1737 with a foreword by Boerhaave and Gaubius. This book was written in Dutch: ‘Alles in Hollandse, des Auteurs Moedertale’ (All in Dutch the author’s mother tongue). This can be considered one of the first signs that Latin as the scientific language was challenged. Reinier de Graaf (Schoonhoven, baptized 30 July 1641–Delft, buried 17 August 1673) was a gynaecologist and gastrointestinal physiologist at Delft. He is 2011 The Authors Acta Physiologica 2011 Scandinavian Physiological Society, doi: 10.1111/j.1748-1716.2011.02286.x 1 Physiology in the Netherlands Æ N Westerhof Acta Physiol 2011 Figure 1 Physiology in the Netherlands: main events. best known for his studies of the function of pancreas in the living dog. His Roman-Catholic faith excluded him from a professorship. • Anthonie van Leeuwenhoek (Delft, 24 October 1632–Delft, 26 August 1723); was a so-called ‘Physicist’ at Delft. Van Leeuwenhoek was educated as a bookkeeper and casher in Amsterdam. He started his rather lucrative drapery business in Delft in 1654. Having expertise in glass blowing, he made his own single-lens microscopes with a better resolution than the microscopes consisting of objective and ocular of the time as used by Swammerdam. Van Leeuwenhoek observed, among others, muscle fibres, bacteria, spermatozoa and blood flow in capillaries and corresponded his findings from 1674 through ‘Sendtbrieven’, to the Royal Society and was elected as a member of the Royal Society (London) in 1679/80. He died a rather rich man. • Herman Boerhaave (Voorhout, 31 December 1668– Leiden, 23 September 1738) received his doctoral degree from the University of Harderwijk. He held, for some time, three of the five professorships in medicine at the University of Leiden. He was a botanist (director of the botanical garden at Leiden), chemist, humanist and a physician of world fame. He held the thesis that the pathology of an organ can only be understood from knowledge of its normal function. We can consider him as the founder of clinical teaching. His main achievement was to demonstrate the relation of symptoms to lesions. He had great interest in physiology, but was not a pure physiologist. However, as we will see that in the middle of 19th century physiology was initiated and begun by clinicians to give medicine a scientific basis, we mention him here. • Jeroen Gaub (Hiëronymus David Gaubius, Heidelberg, 1705–Heidelberg 1780) studied, for personal reasons in the Netherlands at the University of Harderwijk, then went to Leiden, where he was a student of Boerhaave. He held the scientific proof that mind affects body and body affects mind. In 1758, his textbook of pathology (in Latin) appeared that Figure 2 Physiologists of the first Golden Age of Physiology in the Netherlands. 2 2011 The Authors Acta Physiologica 2011 Scandinavian Physiological Society, doi: 10.1111/j.1748-1716.2011.02286.x Acta Physiol 2011 remained the standard text of pathology for almost 100 years. I believe the medical researchers of this ‘Golden age of physiology’ can be called physiologists, even though their interests were many. The physiologists were very well informed about new theories and developments, and Harvey’s model of the circulation was readily accepted. In other words, these researchers had international contacts and also knew each other. Most of them travelled, three were foreign born. Van Leeuwenhoek may not have travelled much but his international contacts were very good, especially his membership of the Royal Society of London. By the end of the 18th century, the scientific language changed from Latin to Dutch. Consolidation 1750–1850 After 1750 a standstill followed. This so-called ‘Consolidation’ period lasted for about 1100 years (Lindeboom 1981). It was not a local phenomenon but was generally seen in Europe in the (medical) sciences. It was especially clear in the Netherlands as can be seen from the following examples. While the use of thermometer in the clinic was introduced by Anton de Haen, a pupil of Boerhaave in the middle of 18th century in Vienna, and used in daily clinical practice, this instrument was not used in Utrecht until 100 years later. Also in the middle of 19th century, the microscope was not introduced to medical students in Leiden. Teaching in physiology consisted of reading Latin texts (Gaubius’ textbook was still the standard); also auscultation (invented by Auenbrugger and introduced in the clinic by Laënnec in 1819) was not or hardly used in 1850. The origin of standstill of medical sciences seems to be the result of rise in philosophical idealism in Germany, mainly under the influence of I. Kant’s (1724–1804) and F.J.W. von Schelling’s (1775–1854) ‘Natur Philosophie’: the intelligent human is able to understand the natural phenomena; experimental, science-based approach, is not necessary (Lindeboom 1981). Around 1840, a number of young medical doctors in Germany became proponents of the concept ‘medicine = science’ and proposed that science should be introduced into the medical curriculum. This ended the romantic philosophical period, in part also thanks to Rudolf Virchow (1820–1902), founder of cellular pathology. Especially his text Die Cellularpathologie in ihrer Begründung auf physiologische und pathologische Gewebelehre (‘Cellular pathology as the basis of physiological and pathological histology’) of 1858, where the cell was introduced as the smallest unit of the organism, made it convincingly clear that most N Westerhof Æ Physiology in the Netherlands diseases are based on the cellular processes. This concept helped to convince the medical profession that physiology, as it was perceived then, forms the basis of (internal) medicine and should be introduced in the medical curriculum. Second golden age of physiology 1850–1975 New names By the end of 18th century, some need existed to intensify communication and exchange. This resulted in the foundation of a number of ‘Genootschappen’ (Societies). One of them is the still existing ‘Genootschap ter bevordering van de Geneeskunde’ (Society for the promotion of Medine) that later was extended to ‘Genootschap ter bevordering van Natuur-, Genees- en Heelkunde’. However, in the middle of the 19th century, a real strong revival of the sciences (Charles Darwin, 1859, the Origin of Species; Dmitri Mendelejev, 1869, the periodic table) and the strong growth of technology (steam locomotives and railroads, first steel steamship crossed the Atlantic, 1852) took place all over Europe. Several specialized branches of the medical sciences arose: gastrointestinal physiology (William Beaumont, 1785–1853); pathology and cell physiology (Rudolf Virchow, 1820–1902); bacteriology (Louis Pasteur, 1822–1895, Ignaz Semmelweis, 1818–1865 and Robert Koch, 1843–1910). In integrative physiology, it is Claude Bernard (1813– 1878) who can be considered the first true general physiologist, but others were prominent too: Ivan Pavlov, 1849–1936 psychophysiology; Charles Sherington, 1857–1952 (neurophysiology), Carl F.W. Ludwig (1816–1895) and Ernest Starling, 1866–1927 (cardiovascular physiology and hormones), Henry P. Bowditch 1840–1911 (1871, first physiological laboratory for students in the USA). New journals In the middle of the 19th century also many new journals of physiology originated. In Germany in 1835, the Archiv für Anatomie, Physiologie und wissenschaftliche Medicin (until 1876) was founded. In 1842 and 1844, the Archiv für physiologischen Medicin and the Zeitschrift für rationelle Medicin followed. In 1847, the Archiv für pathogische Anatomie und Physiologie und für klinische Medicin, was founded by R. Virchow and B. Reinhardt (now called Virchows Archiv). In 1854, Albrecht von Graefes Archiv für Ophthalmologie (now called Graefe’s Archive for Clinical and Experimental Ophthalmology) was founded; and in 1862 Fresenius’ Journal of Analytical Chemistry, 2011 The Authors Acta Physiologica 2011 Scandinavian Physiological Society, doi: 10.1111/j.1748-1716.2011.02286.x 3 Physiology in the Netherlands Æ N Westerhof Acta Physiol 2011 originally called Zeitschrift für analytische Chemie started. Pflügers Archiv (now Pflügers Archiv European Journal of Physiology) started in 1868, while the Journal of Physiology (London) was established in 1878; and somewhat later, in 1898 the American Journal of Physiology was begun. The Journal de Physiologie (Paris) began in 1906. At present there exist more than 120 journals with the term ‘physiology’ in their title. The Nederlands Tijdschrift voor Geneeskunde (the Netherlands Journal of Medicine, NTvG), founded in 1857, played an important role in the communication between physiologists, and between physiologists and clinicians in the second half of the 19th and early 20th century. Table 1 (Heteren van 1991) gives an overview of the (retrievable) publications of the professors of physiology between 1850 and 1950 of the four original medical schools. It may be seen that the NTvG was used for more general information as well as for publication of research articles. The sections in the journal, next to Research, namely News, Opinion, Clinical practice, Perspectives and Varia, contain many subjects of more general interest on which the physiologists had an opinion. The interest of the physiologists in general aspects of society, medicine and education with respect to research is also made quantitative in Table 1. Most physiologists published their research articles in German journals. Einthoven published only six articles on research in the NTvG, but 33 articles in international journals. It should also be noted that most research articles of the physiologists, quite contrary to present day articles, were singleauthored. The Netherlands makes up its arrears The international change affected the Netherlands as well, where it was given extra impetus after the, (un?) founded, publication by Moleschott, (then at Heidelberg, originally from Leiden, later in Italy) that medical sciences in the Netherlands were running behind compared with other European countries. The Dutch originator of the change appears to be J.L.C. Schroeder van der Kolk (1797–1862) with his work in neurology and experimental physiology, but the real driving force of the developments in physiology was F.C. Donders in Utrecht. The law of 1868 by J.R. Thorbecke ended the complex system of diplomas and introduced a single, country-wide, diploma to practice medicine in the Netherlands.

Physiology develops rapidly from 1848 Between 1848 and 1866, all four Universities in the Netherlands that offered a medical curriculum, nominated a professor of physiology and built a research laboratory. The first professors of physiology at the Dutch Universities were: F.C. Donders (Utrecht, 1848– 1869), I. (sometimes J.) van Deen (Groningen, 1851– 1869), A. Heynsius (Amsterdam, 1858–1868). Heynsius later moved to Leiden and was there the first professor of physiology (1866–1885). A complete overview of the professors (chairpersons) of physiology from 1858 to present is given in Table 2. The research performed was very closely related to clinical problems. The clearest example is, of course, Donders at Utrecht who combined, as professor of internal medicine, his clinical duties with his professorship in physiology. It is also interesting to note that the early professors of physiology published on many subjects, usually as single author, and often in the form of rather short publications. Professors of physiology were also involved in more public affairs. Examples are D. Huizinga’s book: Schetsen uit het leven (Images from life); and books for grade school pupils; Hamburger was vice-president of a society to expand permission to enter university for graduates of the secondary school HBS and not only students with a gymnasium (‘latin’ school’) diploma (Gemert van et al. 1989, Westerhof 2010, WWW document). Many physiologists of the first century of organized Dutch physiology (1850–1950) were member of the editorial board of NTvG; A. Heynsius, I. van Deen, W. Einthoven and especially G.A. van Rijnberk who was editor in chief, then called gérant, from 1913 to 1946 (Heteren van 1991, Quak 2005). Figure 3 shows the portraits of the professors (chairs) of physiology until 1950. Teaching. Most teaching of physiology to medical students was in a format of classroom lectures with occasional demonstrations. It was van Rijnberk who, with his appointment in 1909, was the first to organize laboratory teaching, including animal experiments. This was an international trend with Henry P. Bowditch as the first in the USA. Almost all professors wrote or contributed to textbooks of physiology, most of which in Dutch. An example is van Rijnberk’s textbook of physiology in the 1930’s and 1940’s entitled: Neederlandsch Leerboek der Physiologie, which appeared in seven volumes. N Westerhof Æ Physiology in the Netherlands Physiology’s second growth After the Second World War, we see several changes taking place in the universities that affected physiology. Four new medical schools were begun, each with a department of physiology. In 1950, the Vrije University of Amsterdam founded a medical school, after the unsuccessful first start with F.J.J. Buytendijk in 1919 who, in 1925 became professor of physiology in Groningen. The first professor of physiology at the Vrije Universiteit was A.Th. Knoppers, who left after only 2 years for industry, and was succeeded by A.W.J.H. Hoitink in 1953. The (now) Radboud University in Nijmegen started with a medical school including physiology in 1951, where F.J.A. Kreuzer was the first professor. The Erasmus University in Rotterdam began with a medical school in 1966, where M.W. van Hof, was the first professor. Maastricht University founded in 1974, set-off with a medical school with R.S. Reneman as the first professor of physiology. In summary, by 1974 there were eight universities with medical schools in the Netherlands, each with its department of physiology. Physiological research in the Dutch Universities Utrecht University. The physiology in Utrecht, starting with F.C. Donders, was oriented to the sensory system. Originally, vision was the main theme. Donders was a giant in many aspects and had broad interests; he became most famous for his work on vision. Donders was followed by W.Th. Engelmann who was mainly interested in neuromuscular physiology. Engelmann returned to Germany in 1897, and his successor was H. Zwaardemaker who worked on sensory physiology of smell and taste and on phonetics. Both had other interests too: Engelmann studied the isolated heart, and Zwaardemaker studied the biological meaning of radiation with Professor L.P.H. Eijkman, a brother of C. Eijkman who received the Nobel Prize of Medicine or Physiology. His theory of radiation in relation to impulse formation of the heart was shown to be incorrect by Yngve Zotterman. I mention here two physiologists of great fame. Rudolph Magnus (Braunschweig, Germany 1873–Switzerland 1927) was professor of pharmacology at Utrecht University with interest in neuropharmacology and neurophysiology, from 1908 until his sudden death in 1927. Rudolf Magnus worked in Liverpool in 1908 on the physiology of stature-movement and muscle tension. This physiological work made him world famous, and, as was learned 50 years later, it formed the basis of his nomination for the Nobel Prize of 1927. Unfortunately, he died suddenly in the summer of that year. The Rudolf Magnus Institute of Neurosciences is named after him. Herman J.

He attended the 9th International Congress of Physiology in Groningen in 1913 and, through his contact with Magnus, was appointed at Utrecht University, where he became professor in 1915 and full professor in 1918 in physiology/zoology in the school veterinary medicine, and founded an institute (Zoologisch Station Den Helder). He was forced to retire in 1942 in the middle of the Second World War and died in 1943. A.K.M. Noyons, first continued the research line started by Zwaardemaker but, with his successor, J. Jongbloed, got interested in the effects of acceleration on the body. Jongbloed was very interested in space and sports physiology, but also played an essential role in the development of first heart-lung machine. W.L. Mosterd and P.A. Biersteker again were interested in sports physiology, but research in cardiac physiology also took place. H.J. Jongsma shifted the direction to the electrophysiology of the (cardiac) cell. His most important contribution was the electrical interaction of cardiac cells through gap junctions. Integrated cardiac electrophysiology from cell to organism is the research theme at present under the leadership of M.A. Vos. University Groningen. I. van Deen was born in Germany, and educated at Copenhagen University, Denmark. He assumed de name Deen, and performed research neuro-physiology. His successor D. Huizinga was interested in blood and its components, and also in ‘Abiogenesis’ (the study of how life on earth could have arisen from inanimate matter). Subsequently, H.J. Hamburger became professor (Gemert van et al. 1989). He obtained a degree in chemistry followed by 2011 The Authors Acta Physiologica 2011 Scandinavian Physiological Society, doi: 10.1111/j.1748-1716.2011.02286.x 7 Physiology in the Netherlands Æ N Westerhof a degree in medicine under Donders. His general concept was that physico-chemical principles play an important role in physiology and thereby also in medicine. In 1913, he organized the 9th International Congress of Physiology at Groningen, the predecessor of the IUPS meetings (Westerhof 2010, WWW document). F.J.J. Buytendijk after his medical study, changed his interests, via biology and then clinical neurology, to psycho-physiology with the emphasis on psychology. R. Brinkman chaired a section of physiological chemistry from 1933 onwards. This group became an independent laboratory with Brinkman as chairman. While Brinkman concentrated on chemical physiology H.D. Bouman was appointed in physiology and after only 2 years he was succeeded by M.N.J. Dirken. In the following interim period between 1956 and 1960 R. Brinkman was chairman of physiology and in 1960 left to chair the department of Radiopathology. In 1960, the department was split into two, and W.G. Walter and W.G. Zijlstra were appointed as chairs of the two departments of physiology (Walter 1961). Walter’s research was in neuromuscular physiology and Zijlstra’s work was in organ physiology, with emphasis on blood chemistry and oxygen transport. In 1977, Walter was succeeded by C. Rashbass who stayed till 1982. Zijlstra retired in 1990. After an undetermined period, physiology consolidated into a single laboratory of medical physiology with Kernell as chairman. After Kernell left, the physiology as department was dissolved. An institute of neurosciences was formed, where H.W.G.M. Boddeke, since 1998, is responsible for physiology. J.A. Bernards and L.N. Bouman the authors of the textbook Medische Fysiologie were, in later editions (2008), joined by Boddeke. University of Amsterdam. The physiology in Amsterdam began with physiological chemistry of blood, the main interest of A. Heynsius. Later Heynsius also published about the circulation and respiration. Heynsius left after 10 years for Leiden and W. Kühne succeeded him. Kühne was born in Hamburg, now Germany, and studied with all great physiologists of the time: Emil du Bois-Reymond at Berlin, Claude Bernard in Paris, and Carl F.W. Ludwig in Leipzig, now Germany and Ernst W. von Brücke in Vienna, Austria. Kühne was a top researcher working mainly in chemical physiology (of blood) and he coined the word ‘enzyme’. Also nerve-muscle physiology was his interest. T. Place, his successor, published only a few articles on the nervous system. His successor was G.A. van Rijnberk, a very colourful person, was educated in Italy, and had an immense knowledge of art. He was a great teacher both feared and adored by the students but was more a teacher and organizer than a 8 Acta Physiol 2011 researcher. He published only a few research articles but edited a textbook of physiology. (see above). He was editor in chief of the Nederlands Tijdschrift voor Geneeskunde from 1913 to 1946, and his editorial comments were many (hundreds). When he celebrated his 25th anniversary of his professorship, an overview of his work was published in the book entitled: Een greep uit het werk van van Rijnberk (1934). His successor, J. ten Cate, who was born in St. Petersburg, Russia, and a descendant of Dutch merchants that moved to Russia in the 18th century. He studied medicine in Moscow, Berlin and Paris. He worked with Pavlov in St Petersburg before coming to Amsterdam, which influenced his research interests: conditional reflexes and electroencephalography are keywords of his research. J.Th.F. Boeles and L.N. Bouman were, interchangeably, chairman of the department of physiology. Boeles studied nerve action in the broadest sense, from motor nerves to sympathetic nervous effects on the heart. Bouman’s main research was the electrophysiology of the heart, with emphasis on the pacemakers and the conduction system. Bernards and Bouman wrote the textbook Fysiologie van de mens. In later editions, Boddeke joined them and the title changed to the present one: Bouman, Bernards en Boddeke, Medische Fysiologie (2008). After the retirement of Boeles and then of Bouman, the position remained open for a few years, but in 2001 H.J. Ravesloot filled the position of professor of physiology. His main interest was cellular physiology. In 2009, the department of physiology merged with the department of anatomy and embryology to form the department of Anatomie, Embryology and Physiology. Leiden University. A. Heynsius, became the first professor of physiology in Leiden, after having this position for 10 years in Amsterdam. Physiological chemistry of the blood and its constituents was his primary interest and later he also published about the circulation and respiration. His successor was W. Einthoven, who defended his doctoral thesis in Utrecht under the supervision of F.C. Donders, and became full professor of physiology at the age of 25 in 1885. Einthoven was most famous through his work on electrocardiography for which he received the Nobel prize in 1925. The study of electrocardiography required physical and technical expertise, which Einthoven picked up during his medical studies when he worked with physicists like C.D.H. Buys Ballot and others. Next to the electrical phenomena of the heart he was interested in neurophysiology, especially the influence of the brain on body position and movement. Einthoven was succeeded by G.G.J. Rademaker, neurophysiologist and neurologist, who was a pupil of Rudolf Magnus (Braunschweig, Germany 1873–Switzerland 2011 The Authors Acta Physiologica 2011 Scandinavian Physiological Society, doi: 10.1111/j.1748-1716.2011.02286.x Acta Physiol 2011 1927). Magnus was professor of pharmacology at Utrecht University with interest in neuropharmacology and neurophysiology, from 1908 until his sudden death in 1927. The Rudolf Magnus Institute of Neurosciences is named after him. He wrote textbooks in German, French and English (sensory system, vision, hearing and vestibular function). In 1946, he left physiology for neurology. Between 1946 and 1969, J.W. Duyff was the professor of physiology at Leiden. He played an important role in the resistance movement during the Second World War. He was a very good organizer, and was editor in chief of Acta Physiologica et Pharmacologica Neerlandica from 1950 to 1969. He was (vice-) editor of the Nederlands Tijdschrift voor Geneeskunde (NTvG) from 1956 to his sudden death in 1969. His main interests were vision and audition and his articles were mostly published in Acta Physiologica et Pharmacologica Neerlandica and the NTvG. He also wrote a short review on Dutch physiology (Duyff 1952). Professor Duyff as chairman of Physiology organized the now appropriately called 22nd IUPS meeting in Leiden in 1962. Duyff was succeeded by G.J. Tammeling, and under his chairmanship four groups were formed: biological chance processes; chronobiology and the adaptation to the external milieu; respiratory physiology and physiological physics. W.J. Rietveld who was Tammeling’s successor was interested in and published many articles on chronobiology. The physiology became part of a department of clinical sciences in 2000. VU University Amsterdam (formerly Vrije Universiteit of Amsterdam). After the first attempt to start a school of medicine (1919–1924), the medical school at the Vrije Universiteit (Now called VU University) started in 1950. A.Th. Knoppers was the first professor of physiology, but left for industry in 1952. His main interest was pharmacology. A.W.J.H. Hoitink succeeded him in 1953; he was a physiologist with very broad interests and recently retired from Batavia (Indonesia). One of his research subjects was ballistocardiography, then a newly proposed technique (Jongbloed 1951) given a physical basis in Utrecht by H.C. Burger and A. Noordergraaf. A.A. Knoop, his successor began in 1969 and initially continued this research direction. However, ballistocardiography was too complex for interpretation and clinical application. It was therefore decided to concentrate the entire laboratory on cardiovascular physiology, with strong emphasis on haemodynamics. After a bridging period of 2 years by N. Westerhof, G.J. Tangelder, member of the department of physiology at Maastricht University, became chairman of physiology. Presently, the department covers cardiovascular physiology from molecule to organism. N Westerhof Æ Physiology in the Netherlands Radboud University Nijmegen (formerly Catholic University Nijmegen). With the foundation of the school of medicine in, what is now called Radboud University, professor F.J.A. Kreuzer was chosen as head of the department of physiology. Kreuzer came from Switzerland, worked in the departments of physiology at Fribourg, Switzerland, Sheffield, UK and Dartmouth NH USA, before coming to Radboud University. His main interest was oxygen transport by blood and diffusion, and he developed oxygen electrodes. J.A. Bernards treaded in the steps of Kreuzer and worked mainly on the effects of pulmonary gas embolism on circulation and respiration. Bernards, with Bouman, and later Boddeke are the authors of the textbook Medische Fysiologie (Bouman et al. 2008). Bernards was followed by C.H. van Os and his interest was the physiology of water and salt management and cell biology of the kidney. R.J.M. Bindels succeeded van Os and carries out research on transport physiology in epithelia of the kidney and intestine, especially the molecular and cellular physiology of electrolyte transport. Presently, the department of physiology exists of three research groups: integrative physiology, ion transport and osmoregulation. Erasmus University Rotterdam. The department of physiology started in 1966 with Professor M.W. van Hof as chairman. Van Hof studied the physiology of brain function in the widest sense. He retired in 1993 and his successor was H. Collewijn who mainly studied vision and the vestibular system. In 2002, the department was dissolved and became part of Neurosciences. Maastricht University. In 1974 with the start of new university at Maastricht, R.S. Reneman founded the physiology, and was soon joined by F.I.M. Bonke. Reneman was educated as an anaesthesiologist in Utrecht and worked several years with Janssen Pharmaceutica before joining Maastricht. The research was concentrated on the cardiovascular system, namely, electrophysiology of the heart, cardiac and large artery function, and with special attention to the microcirculation. Also the development of ultrasound techniques should be mentioned. M.A. Allessie, followed Reneman in 1990, and he studied electrophysiology of the heart with special emphasis on atrial fibrillation. Presently, M.A. Post is chairman of the department and his main research interests are angiogenesis/collateral formation and vascular healing and remodelling after arterial injury. Societies and meetings International. Following the decision of a group of physiologists in 1885 regular, international, meetings of 2011 The Authors Acta Physiologica 2011 Scandinavian Physiological Society, doi: 10.1111/j.1748-1716.2011.02286.x 9 Physiology in the Netherlands Æ N Westerhof physiology started with the 1st International Congress of Physiology at Basle, Switzerland, in 1889. These meetings were held every third year (excepting 1916, 1941 and 1944), and physiologists from Europe and the America’s participated. The last, 18th meeting, was held in 1950 in Copenhagen Denmark. Subsequently, the international meetings were organized by the International Union of Physiological Scientists. These meetings, being a continuation of the international congresses started in 1953, with the first IUPS meeting counted as the 19th congress. After 1989 the IUPS meetings were held every 4th instead of every third year. The 37th meeting will be in Birmingham, England in 2013. In 1913, Hamburger organized the 9th International Congress of Physiology at Groningen (Westerhof 2010, WWW document). The number of participants was 594 and 150 presentations (26 from the Netherlands) were given. The prize for the best Dutch doctoral dissertation is named after Hamburger and is awarded yearly since 1987, by the Netherlands Society of Physiology. Among the presentations of this meeting was one by J.G. Dusser de Barenne (1885–1940). Dusser de Barenne studied medicine in Amsterdam, worked and was lecturer at Utrecht University and went to Yale (New Haven, CT, USA) in 1930 to set up a laboratory of neurophysiology. He died of coronary disease in 1940. The oeuvre-award of the Netherlands Society of Physiology is named after Dusser de Barenne. Professor J.W. Duyff chairman of Physiology at Leiden organized the, now appropriately called 22nd IUPS meeting in Leiden in 1962. This was a very large international congress. Europe. As the forming of FEPS, the Federation of European Physiological Societies (Federation European Societies of Physiology, FEPS 1991, WWW document), there are also meetings for mainly European physiologists. Presently, the physiological societies of 31 countries (counting England and Ireland as 1) contribute to the FEPS. The first three meetings were in Maastricht (1995), Prague (1999) and Nice (2003). Subsequently, so-called joint meetings were organized by a combination of host country and the FEPS. Examples are the joint meeting of the Physiological Society and FEPS in Bristol, UK (2005); the German Physiological Society and FEPS, Munich Germany (2006); the Slovak Physiological Society and FEPS, Bratislawa, Slovakia (2007); the Slovenian and Austrian Physiological Societies and FEPS, Ljubljana Slovenia (2009). The following joint meetings are planned: the German-Scandinavian Physiological Societies and FEPS, Copenhagen, Denmark (2010); the Turkish Physiological Society and FEPS, Istanbul, Turkey (2011); the Spanish Physiological Society and FEPS, Santiago de Compostela, Spain 10 Acta Physiol 2011 (2012); the Hungarian Physiological Society and FEPS, Budapest, Hungary (2013). The journal of the FEPS is Acta Physiologica, formerly the journal of the Scandinavian Physiological Society: Acta Physiologica Scandinavica. National. The first, founding, meeting of the Nederlandse Vereeniging voor Physiologie en Pharmacologie (Netherlands Society of Physiology and Pharmacology) was held April 15, 1916 (van Rijnberk 1916). It was the first ‘Day of Physiology’, a whole day (Saturday) with about 100 participants: physiologists, practicing physicians and medical students. The start of this society shows a definitive break with anatomy. About 1950 the society’s name changed from Nederlandse Vereniging voor Physiologie en Pharmacologie to Nederlandse Vereniging voor Fysiologie en Farmacologie, to adhere to the changed Dutch spelling rules. In 1975, the Nederlandse Vereniging voor Fysiologie en Farmacologie decided to rearrange their organization by splitting into two sections: Physiology and Pharmacology, but continuing as a single society. However, nice an idea, in 1979 an official divorce followed, and from then on physiologists were united in the Nederlandse Vereniging voor Fysiologie. National meetings. The members of the Nederlandse Vereeniging voor Physiologie en Pharmacologie convened several times per year up to about 1960. The meetings were announced in the Nederlands Tijdschrift voor Geneeskunde, and the location rotated between the universities. Occasionally, a foreign sister society was invited. For instance, in 1925 a meeting was held in Leiden, with members of the ‘Physiological Society’ of the UK. That meeting included a visit to Amsterdam. In 1958, the meeting was held in Amsterdam together with the Belgisch Genootschap voor Fysiologie (Belgian Society of Physiology), and in 1975 there was a combined meeting in Gent with the Belgisch Genootschap voor Fysiologie. In 1959, the Nederlandse Federatie van Medisch en Biologische Verenigingen (Dutch Federation of Medical and Biological Societies) started to organize meetings broader than physiology alone, mainly animal biology, in the Netherlands, and many physiologists participated in these meetings. However, it was felt that a regular exchange of developments in physiology was more useful, and in 1973 yearly meetings of the Nederlandse Vereniging voor Fysiologie began. Papendal symposia The first so-called Papendal-meeting was organized in 1973, they were fall meetings. This meeting evolved, in 1984, into a 2-day symposium of physiology, without 2011 The Authors Acta Physiologica 2011 Scandinavian Physiological Society, doi: 10.1111/j.1748-1716.2011.02286.x Acta Physiol 2011 pharmacology and on a regular, yearly, basis. The later started Young Physiologists Day (1997) was originally a separate meeting in the spring, where the young physiologists could exchange ideas with presentations and posters. In 2004, this Young Physiologists Day was incorporated in the Papendal Symposium. Thus, from 2004 the Papendal Symposium is a 2-day symposium, in early December, with the first day devoted to the Young Physiologists, and in the evening the lecture of the Hamburger Prize recipient. The second day is on a general aspect of physiology with Dutch and foreign expert speakers. While the location, the conference centre Papendal, will be changed the name of the yearly meeting will remain as known as Papendal-meeting. Physiologists convent In 1961, the question arose how (some) medical students who wished to be a physiologist should be educated. This idea was based on a similar action of the pharmacologists. Also there was a proposal to organize a country-wide first year of the medical curriculum. To discuss these matters and other, more general aspects, such as nominations of new Professors of physiology in the Netherlands, professor Boeles chairman of physiology at the university of Amsterdam and on suggestion of Prof. J.W. Duyff at Leiden, in 1966, asked all colleagues (seven at the time, and eight after 1974) to form the Physiologists Convent. To keep the number of participants small it was decided to let one representative per university participate. It turned out that this was almost always the department chairman. The convent started to make an inventory of the physiology courses in the different universities, but found that the physiology curriculum differed too much to come to a core curriculum. Other subjects, such as the problems with Acta Physiologica et Pharmacologica Neerlandica were also discussed (see below). After the 1980’s the meetings were held less and less frequently. The impression is that the convent was not sufficiently united and did not sufficiently emphasize the importance of physiology in research and, especially teaching. Publications Writing format of articles. Up till the Second World War most scientific publications of the Dutch physiologists were in German journals and only few were in French and English journals, Also a substantial number of publications appeared in the Nederlands Tijdschrift voor Geneeskunde. Originally scientific articles were based on a format, where the authors’ thought processes that gave rise to the results were presented and defended in the order in which the experiments were carried out (Suppe 1998). N Westerhof Æ Physiology in the Netherlands See for example the article by Engelmann (1870). This argumentative structure was gradually abandoned in the early 20th century. Now, the generally accepted format of articles appeared in the American Journal of Physiology in the early part of the 20th century and it became standard after in the 1930s. In the Netherlands, this format was then not commonly accepted yet. See for instance the article by Duyff (1946) and compare it with a modern article. However, in the 1950s this standard form of articles became common in the Netherlands as well. Dutch journals. With the start of organized physiology in 1916 (van Rijnberk 1916), it was still generally felt that publications had to appear in Dutch contexts. The Archives Néerlandaises des Sciences Exactes et Naturelles, published by ‘la Société Hollandaise des Sciences à Harlem’ started in 1866 and lasted until 1911. In 1918, a successor journal was started, entitled: Archives Néerlandaises de Physiologie de l’Homme et des Animaux. In 1927 Archives Néerlandaises de Phonétique Expérimentale (1927–1947) split off, and in 1931 another journal appeared entitled Acta Brevia Neerlandica de Physiologia, Pharmacologia, Microbiologia (in short Acta Brevia). It was a merger of Archives Néerlandaises de Physiologie and Acta Brevia that formed, in 1950, the Acta Physiologica et Pharmacologica Neerlandica. This new journal, with J.W. Duyff as editor in chief, was very modern in layout. It appeared four times a year, the languages were English, German and French, but most articles were in English. Abstracts were presented in three languages. The journal also published abstracts of the meetings of the Nederlandse Vereniging voor Fysiologie en Farmacologie, and can be considered as the journal of the Netherlands Society of Physiology. By 1968, it became clear that Dutch researchers were more and more preparing their articles for international English-language journals, and that Acta Physiologica et Pharmacologica Neerlandica, having a rather small number of subscribers, could not attract enough articles. Meanwhile Pflügers Archiv was exploring changing into a European Journal of Physiology. In a letter to the editors of Pflügers Archiv by Boeles as chairman of the Physiologists Convent, it was mentioned that Acta Physiologica et Pharmacologica Neerlandica was ‘in der Agone’ (in agony). However, the Dutch Physiologists Convent was hesitant and no countries supported this idea of making a European Journal of Physiology, and a new European journal was not formed. In January 1975, Pflügers Archiv was indeed transformed into Pflügers Archiv European Journal of Physiology (First volume 361). The last volume (number 15) of the Acta Physiologica et Pharmacologica Neerlandica appeared in 1969, and the journal was absorbed by European 2011 The Authors Acta Physiologica 2011 Scandinavian Physiological Society, doi: 10.1111/j.1748-1716.2011.02286.x 11 Physiology in the Netherlands Æ N Westerhof journal of Pharmacology in the same year. The titles of the articles in Acta Physiologica et Pharmacologica Neerlandica can be found in PUBMED, but the abstracts and full articles of the journal are not electronically available. However, paper versions are obtainable in the university libraries of Leiden and VUmc library. Between 1907 and 1957, the Dutchlanguage journal Tijdschrift was in existence. The editor was van Rijnberk and the journal was mainly meant for the broad general public. The Nederlands Tijdschrift voor Geneeskunde still exists but is presently little used by physiologists for publication. Loss of identity? Professors of physiology performed not only teaching and research but had also societal interest (see Table 1). They mainly published in the ‘Nederlands Tijdschrift voor Geneeskunde’, and not only research articles but also notes and papers on general subjects. Also physiologists regularly published in newspapers about developments in medicine, especially in the late 19th and early 20th century. A later example is J. Jongbloed who wrote regularly in Utrechts Nieuwsblad (the daily newspaper of Utrecht) about space physiology. Furthermore, professors of physiology worked in general very closely with clinical researchers, this was how physiology was initially started, namely to give medicine a scientific basis. After Second World War, especially in the 1960s and 1970s the number of (medical) students increased enormously. Also societal relevance of the medical research became more and more important. In the same period, research in the medical sciences became divided in a number of specialized areas. This was, in part, the result of the great successes in cell biology, molecular biology, and somewhat later genomics and protein biology. In 1977, the American Physiological Society decided to split the American Journal of Physiology into a number of sections. This decision was unavoidable as specialization of researchers made it impossible for them to read all news in physiological research. Nevertheless, these developments resulted in decrease in recognition of physiology as the science of ‘functions and vital processes of living organisms, their parts and organs’. From the 1980’s researchers, including professors where evaluated on the basis of research articles (especially citations), leaving, next to teaching, and the increased administrative duties, even less time for other activities. For example, J.W. Duyff was the last physiologist who was (vice)-editor in chief of the Nederlands Tijdschrift voor Geneeskunde. Also the Physiologists Convent did not propose a united country-wide programme for teaching and research had grown too far apart from direct clinical 12 Acta Physiol 2011 applications, it became almost a separate discipline (too little translational research). These observations may have led to the idea that there is no need for separate departments of physiology. At present the translation of the enormous amount of knowledge gathered in sub-branches of biology such the cell, molecule and gene is not sufficiently studied in the context of the function of the organ or organism as a whole. At the cellular level ‘systems biology’ was started about 1990, where an interaction of many complex mechanisms is combined to understand overall cellular function. This approach requires the use and construction of computer models (Alberghina & Westerhoff 2008). Also, recently NOW the Nederlandse Organisatie voor Wetenschappelijk Onderzoek (NWO) with the programme ‘Centres for Systems Biology Research’ stimulates and funds research from molecule to organism. Luckily physiology at the organ and organism level is moving in that direction as well. To better understand the physiology the step upwards to the organ or organism is made through the so-called physio(no)me (Bassingthwaighte 2000). Future Research. In his review, C.A. Pekelharing (1848–1922, professor of physiology, comparative anatomy and pathology at Utrecht University) in 1907 made it clear that the good medicine is based on the scientific approach (Pekelharing 1907). From the 19th to far in the 20th century physiology was the leading basic science and was integrated with the clinical sciences. For example, Alfred Noble created the ‘Nobel Prize in Physiology and Medicine’ rather than a prize in medicine. The specialization in the research, i.e. to cell, molecule and gene, moved physiology further away from direct clinical practice. However, it is becoming more and more clear the translation of this basic knowledge to the organ an organism level is necessary. This is not only seen in the IUPS Physiome Project (IUPS), WWW document but also recognized by NWO (the Netherlands Organization for Scientific Research) with its ‘NWO-programme complexity’. At the physiological level this is materializing through the IUPS Physiome Project (IUPS), WWW document, a worldwide public domain effort to provide a computational framework for understanding human and other eukaryotic physiology. A related approach is Computational Physiology (Hunter & Nielsen 2005), from Genome to Physiome or Physionome ‘physio’ (life) + ‘ome’ (as a whole). In short, it appears that collaboration and computers are key words with good translational research as goal. Organization, research and teaching. In 1990, the medical school (‘Faculty’) and the hospital of the 2011 The Authors Acta Physiologica 2011 Scandinavian Physiological Society, doi: 10.1111/j.1748-1716.2011.02286.x Acta Physiol 2011 University of Amsterdam were the first to form a University Medical Center: the Academic Medical Center of the University of Amsterdam, the AMC. By the late 1990’s and early 2000’s all Dutch Universities had followed. The basic sciences like physiology and anatomy originally departments of the University, became part of the Academic Medical Center or the University Medical Center, as well as the clinical departments. The research in physiology in the Netherlands is thus forced to make its research efforts more translational, and physiology as a ‘stand alone’ scientific approach will probably disappear. I see a future for physiological research as a strong translational field between genetic/ cellular research and its clinical applications, but not necessarily taking place in separate departments of physiology. The teaching in the University Medical Centres is more and more organized on the basis of organ systems, where cell, anatomy, physiology and clinical specialties all participate. This construction makes physiology as an entity less clear. However, the subjects should not disappear and be given by physiologists. Thus, the departments of physiology also have an opportunity to not only integrate their classroom teaching but also build up, together with the clinical departments, practical courses. A report released by the Association of American Medical Colleges (AAMC) in June 2009, entitled: Scientific Foundations for Future Physicians, emphasizes that physicians must have a firm grounding in the biomedical sciences and understand their relation to the physical sciences and mathematics (Long & Alpern 2009). This is an approach, where the teaching by the physiologist is essential. The physiologist as teacher should integrate these subjects to improve understanding the function of the organs and organism. The physiologists should also keep in mind that their teaching may help in the education of physicianscientists. Most often, physician-scientists either become pure clinicians or focus all of their energy on basic sciences, thus playing the same role as PhD-trained biomedical scientists, while they should form the core of the translational research effort. I urge the physiologists in the Netherlands to make a teaching programme that convinces the directorates of the University Medical Centers in the Netherlands that physiology is indispensable in the medical education. The teachings should not only confer essential physiological knowledge to all medical students but should also prepare, even a few of them, for future collaborative research between clinicians and physiologists. Departments may disappear but physiology does not and physiologists are indispensable. N Westerhof Æ Physiology in the Netherlands Conflict of interest None.
