Rudolf Virchow (1855)
German biologist Rudolf Virchow stated the third tenet of the cell
theory, "omnis cellula e cellula" which translates to "every cell stems
from another cell". He also discovered that, during times of illnesses,
it is not the whole organism who is sick, but rather only a certain
group of cells.Hans and Zacharias Jansen (1590)
