HISTORY OF CELL DISCOVERY Late 1600s 1500s Early 1600s 1665 1830s Rudolph Virchow: Looked at Invented 1) 2) Zoologist that said: Botanist that said: and called them • The cell is the basic unit of life • Anton Van Leeuwenhoek • Hans & Zaccharias Janssen • Pond water • MatthaisSchleidan • All living things are made of 1+ cells • Plants are made of cells • Cells Also looked at Leads to Cell Theory: 1) 2) 3) And called the swimming microbes: • Theordor Schwann • All cells come from pre-existing cells • Used hand lenses to assess cloth quality • Robert Hooke • High quality lenses • First light microscope • “Animalcules” • Physician that studied cancer • Thin slices of cork • Invented 1st crude microscope • Animals are made of cells
