The legacy of Leonardo Da Vinci has contributed to the science
that we have today. From simply taking a trip through a helicopter to
viewing the current time from a clock, Leonardo Da Vinci made this
possible. Da Vinci was a man of many talents and interests. He’d spend
his lifetime painting unusually artistic figures or engineering a new
design for an innovation that will contribute to scientific advancement.
He was regarded as the, “Renaissance Man”.
Da Vinci was one of the first scholars to study friction and its
contribution to machines. He explored all kinds of friction. He also
drew a distinction between sliding and rolling friction. He stated two
laws of friction: (1) the areas in contact have no effect on friction. (2) If
the load of an object is doubled, its friction will also be doubled
(Tribology).
Da Vinci explored plate tectonics in a different perspective than that of
many contemporary geologists, which helped discover the gradual
shifts from coastlines are valid.
Da Vinci innovated the revolutionary “Self-Propelled Car." This
innovation contributed to the production of cars with advanced
technological innovations.
Da Vinci created the “Aerial Screw” which was a design of a
helicopter. This contraption contributed to the actual helicopter today.

Anton van Leeuwenhoek
Anton van Leeuwenhoek was called the father of microscopy.
He contributed a lot to microscope use and design.
From Holland. Lived 1632-1723
Worked in a dry goods store where threads on cloth were counted using a
magnifying glass. He worked on the lenses and modified the to 270x diameters
which were the finest at the time.
This led to him starting to build microscopes. These were the first practical
microscopes.
He was the first to see and describe bacteria (1674), the life in a drop of water, yeast
plants, blood circulation and more.
Sent over 100 letters to the Royal Society of England and the French Academy
describing his findings.
"My work, which I've done for a long time, was not pursued in order to gain the
praise I now enjoy, but chiefly from a craving after knowledge, which I notice
resides in me more than in most other men. And therewithal, whenever I found out
anything remarkable, I have thought it my duty to put down my discovery on
paper, so that all ingenious people might be informed thereof." - Anton Van
Leeuwenhoek Letter of June 12, 1716
None of his gold and silver microscopes have been recovered. The were sold off
after he died.
Tradesman from Delft, Holland.
No fortune or higher education, university degrees or other languages.
Discovered bacteria and cells
Made over 500 microscopes, less than ten around today.
Strong magnifying glasses, not compound microscopes used today
Gabriele Fallopius
• Italian anatomist in the 16th century
• Born in 1523 in Modena and died on October 9, 1562 in Padua
• Grew up in poverty but later rose above it to become what he is known
for today
• Studied medicine and later became a professor at Ferrara
• He studied with one of the greatest anatomists who gave the foundation
for anatomy, Andreas Vesalius
• Also got to study at one of the best anatomy schools on Europe at the
time and later teach at as well, which is Padua.
• Got published in Observations anatomical for his anatomy research
• First person to discover and describe the semicircular canals, pauper's
ligament and the male and female reproductive organs
• When he joined forces with Vesalius to argue against the principle
ideas of Galen, the views of the people shifted in medicine, which was
one of the reasons medicine is how it was in the Renaissance period
• Fallopius founded and named many organs in the body including the
vagina, placenta, clitoris and many more
• Described the fallopian tubes as “trumpets of the uterus”

Bartolommeo Eustachio
Bartolommeo Eustachio is an Italian anatomist who is known as one of the
fathers of modern anatomy (1520-1524) He was noted for the heart and
the ear. He settled in Rome and made several anatomical discoveries
including the tube from the middle ear and the mouth, and a valve on the
right of the auricle both are called Eustachian after him. Eustachio was
born in San Severino in eastern Italy. Scholars have placed his birth date
from 1510 to 1524. His father was Mariano, a physician, and he gave him
an excellent education, which included studying Greek, Hebrew, and
Arabic.
He studied to become a doctor at the Archiginnasio della Sapienza in
Rome, and he beginning his practice around 1540.
He became the physician to Cardinal Giulio della Rovere in 1547. In 1549,
Eustachio went to Rome with Cardinal Rovere. There he became a
professor of anatomy at the Archiginnasiodella Sapienza. Because of his
position, he was able to obtain human cadavers for dissections.
Religious practices for the body made human anatomical studies really
difficult to the extent that doctors could not legally dissect human corpses
for many centuries. The problem began to ease during the start of the
Black Death pandemics, which arrived in Europe around 1348. The popes
wanted to know what caused the devastating disease, so they permitted
postmortem examinations of plague victims. But it was almost 200 years
later, in 1537, before Pope Clement VII allowed human dissections in
normal anatomy classes.
William Harvey
• Harvey was an English physician who was the first to
describe accurately how blood was pumped around the body
by the heart. Harvey was also the first to suggest that
humans and other mammals reproduced via the fertilization
of an egg by sperm. It took a further two centuries before a
mammalian egg was finally observed, but nonetheless
Harvey's theory won credibility during his lifetime.
• Harvey, William was an English physician who, by observing
the action of the heart in small animals and fishes, proved
that heart receives and expels blood during each cycle.
Experimentally, he also found valves in the veins, and
correctly identified them as restricting the flow of blood in
one direction. He developed the first complete theory of the
circulation of blood, believing that it was pushed throughout
the body by the heart's contractions. Harvey also noted, as
earlier anatomists, that fetal circulation short circuits the
lungs. He demonstrated that this is because the lungs were
collapsed and inactive.
