Study Notes

Antonie Van Leeuwenhoek

Born in 1632 and died in 1723, known for developing a simple microscope with a single biconvex lens.
First individual to observe living cells, specifically blood cells in frog foot-web capillaries.
Recognized cells as living units of all organisms, though he did not use the term "cells."

Robert Hooke

In 1665, introduced a two-lens microscope to examine various materials.
Studied a thin slice of dead cork, observing box-like structures resembling small cubicles.
Coined the term "cells" based on the resemblance to monks' living quarters in a monastery.
