GUESS
WHAT?
At the end of the session, the students should
be able to:
•discuss the history of microscope
and its uses;
•create a timeline about the history
of microscope;
•identify the use of a microscope.
MICROSCOPE
MICROSCOPE
A piece of laboratory equipment that is
used to magnify small things that are
too small to be seen by the naked eye,
or too small for the details to be seen
by the naked eye, so that their finer
details can be seen and studied.

Take note of the following questions and
answer them using the video that you will
be watching now:
1. Who is the father of Modern Physics and Astronomy?
2. Who built the first usable British compound microscope?
3. What are the two converging lens system of the first compound
microscope?
4. Who discovered the cell?
5. Who is the first person to witness a live cell under a
microscope?
6. Who are the scientists who invented the electron microscope?
7. What type of microscopes be used to examine living cells?

WHEN THE
FOLLOWING EVENTS
HAPPENED:
The Nobel Prize in Physics is
awarded jointly to Ernst Ruska
(for his work on the electron
microscope) and to Gerd Binnig
and Heinrich Rohrer (for the
scanning tunnelling microscope).
1986
Salvino D’Armate is
credited with
inventing the first
wearable eye
glasses.
1284 ad
English physicist Robert Hooke
publishes Micrographia, in which
he coins the term ‘cells’ when
describing tissue. The book
includes drawings of hairs on a
nettle and the honeycomb
structure of cork.
1665
Antonie van Leeuwenhoek builds
a simple microscope with one
lens to examine blood, yeast and
insects. He is the first to describe
cells and bacteria. He invents
new methods for making lenses
that allow for magnifications of
up to 270 times.
1676
Ernst Ruska and Max Knoll design and
build the first transmission electron
microscope (TEM), based on an idea
of Leo Szilard.
The electron microscope depends on
electrons, not light, to view an
object. Modern TEMs can visualise
objects as small as the diameter of
an atom.
1931
Nobel Prize in Chemistry awarded
to Eric Betzig, Stefan Hell and
William Moerner for the
development of super-resolved
fluorescence microscopy which
allows microscopes to now
‘see’ matter smaller than 0.2
micrometres.
2014
Zacharias Janssen and his son
Hans place multiple lenses in a
tube. They observe that viewed
objects in front of the tube
appear greatly enlarged. This is a
forerunner of
the compound microscope and
the telescope.
1590
Researchers at UCLA use
a cryo electron
microscope to see the
atoms of a virus.
2010
Stefan Hell pioneers a new optical
microscope technology that allows
the capture of images with a higher
resolution than was previously
thought possible. This results in a
wide array of high-resolution optical
methodologies, collectively termed
super-resolution microscopy.
19931996
HISTORY OF
MICROSCOPE
The first vision aid, called
a reading stone, is
invented. It is a glass
sphere placed on top of
text, which it magnifies
to aid readability.

1986
Nobel Prize
any of six international prizes awarded annually for
outstanding work in physics, chemistry, physiology or
medicine, literature, economics (since 1969), and the
promotion of peace. The Nobel Prizes, first awarded in
1901, were established by the will of Alfred Nobel and are
traditionally awarded on December 10, the anniversary of
his death. The awards are decided by boards of deputies
appointed by Swedish learned societies and, in the case of
the peace prize, by the Norwegian Parliament.
