jul 31, 1665 - Robert Hooke.
An English scientist, born in 1635. He died in 1703.
In 1665, he studied a sheet of cork with a simple microscope like the one you see in the picture below.
The engraving on the left shows one of Hooke’s drawings of his observations of a sheet of cork.
When he saw the small, honeycomb-like compartments on the sheet, Hooke called them “cells” (from the Latin word for small room).
