The beggining of the microscope which helped us learn more about cell biology!



This is a picture of a reading stone.
  The date of this first invention is circa 1000AD. The inventor is unknown. The first technology used to study cell biology was a reading stone. A reading stone engined the words so you could read them better.










the eyeglass
 The second tool that helped us learn more about cell biology was the wearable eyeglass. This eyeglass helped us see things more clearly. It helped magnify letters where they are not as blurry. This was invented by an Italian named Salvino D' Armate in circa 1284.

The third inention was called a telescope. The telescope was invented by Zaccharias Jenssen and his son Hans. This was created in 1590.  It helped make objects far away seem closer.



The next tool invented was the microscope in 1665 by a man named Robert Hooke. He realized when he looked through it he could see holes in a peice of cork.

In 1674 the new tool to study cell biology  simple microscope.
 A man named Anton Van Leeuwhen Hoek made a simple microscop
e so he would be able to look at blood, insects, yeast and other small objects. He was also the first to be able to describe bacteria.

In the 18th century an improved telescope was where two peices of glass were put together instead of just one. This helped with the refraction of light.

In 1830 the prototype of the compound microscope was invented.  Joseph Jackson Lister put several weak lenses together to make one so it does not make the image blurry.

In  1872 the formula that would determine what the maximum resolution possible for a microscope was invented. This was invented by Ernst Abbe.





In 1932 the phase control microscope was invented by Frits Zernike. This allowed him  to study colorless substances.

scanning tunneling microscope
The scanning tunneling microscope was invented in 1981 by Gerd Binnig  and Heinrich. this gave three deminsional objects to fit atomic level.
