The Microscope's History By ifiok sunday-edemidiong

Robert Hooke

Birth

July 28, 1635; Freshwater, Isle of Wight, England

Death

March 3, 1706(aged 67); London, England

Occupation

Physics, chemistry

His Contributions and Cool Facts

Robert Hooke was an English natural philosopher, architect, and polymath. He also studied within the field of physics and chemistry. He dabbled within many fields of science, discovering the laws of elasticity, studied gravitation, horology, astronomy, and created a way to determine longitude. His first Microscope is on display at the National Museum of Health and Medicine in Washington, DC.

Juicy Facts

In a groundbreaking study, he coined the term cell while discussing the structure of cork. Being a true polygraph, Hooke covered many topics during his career including comets, the motion of light, Jupiter's rotations, gravity, human memory, and the properties of air.

Zacharias Janssen

Birth

1585(1580)

Death

1632(1638)

Occupation

Spectacle-Maker, (sometimes a counterfeiter)

His Contributions and Cool Facts

Zacharias Janssen was a Dutch spectacle-maker associated with the invention of the first optical telescope. He is also sometimes accredited with the invention of the the first truly compound Microscope. Spectacle making back then was actually a very secretive and competitive trade. He has been associated with both the single lens optical Microscope and the compound 9x magnification Microscope.

Juicy Facts

Through the years of 1613-1619, Janssen was tried for the counterfeiting of coins. He fled to the neighboring village of Arnemuiden to avoid the penalties for counterfeiting. Though he was caught, and should've been put to death, the trial was delayed allowing him to flee again, the charges finally being dropped against him.

Antonie Van Leeuwenhoek

Birth

October 24, 1632; Delft, Dutch Republic

Death

August 26, 1723(aged 90); Delft, Dutch Republic

Occupation

Microscopist, biologist

His Contributions and Cool Facts

Antonie Philips van Leeuwenhoek began his studies while working in his draper's shop. In wanting to see the quality of the thread better than the then current magnifying lenses available. So he took up an interest in lens making. So, by placing the middle of a small rod of soda lime glass in a hot flame, he created a very small high quality glass sphere. These speheres then became the lenses of his microscope.

Juicy Facts

Antonie made more than 500 optical lenses. He also created at least 25 single lens microscopes, 9 only surviving today. Any of the lenses that have survived today are capable of magnifying objects up to 275 times. There is also a speculation that he might have created a lens that could magnify up to 500 times!
