5h 29min, jan 1, 1855 y - Rudolph Virchow:
-After watching/working with Schleidon and
Schwann, Virchow realized that since all living
things are made from cells, they must be
produced from other cells. In his words, "...all
cells (come) from cells." This means that
Virchow was the last person to contribute to the
cell theory.
