The Cell Theory

By: Michael Freund

Robert Hooke

Robert Hooke was the first man to see, and describe cells. He named them cells, because

he thought they looked like small rooms, because he was looking at a dead piece of cork and the cells weren't alive.

Anton Von Leeuwenhoek

This man was the first to do discover living cells, and found this in 1670.

Theodor Schwann

This man mode the theory: all living things are made up of 1 cell or more, in 1839.

Matthias Schleiden

He determined that all plant tissues are composed of cells and that an embryonic plant arose from a single cell. He did this in 1838.

Rudolf Virchow

Rudolf Virchow's third tenet to the cell theory is this: Omnis cellula e cellula, or all cells develop only from existing cells. He made this theory in 1855.
