Robert Hooke
Robert Hooke, an English scientist, discovered a honeycomb-like structure in a cork slice using a primitive compound microscope. He only saw cell walls as this was dead tissue. He coined the term "cell" for these individual compartments he saw. -
Anton Leeuwenhoek
Anton Van Leeuwenhoek's single most important discovery was the existence of single-cell organisms. While using a microscope to examine pond water in 1674, he observed dozens of protists, which he called 'animalcules,' as well as spirogyra, or green algae .he existence of single-celled organisms not only opened an entirely new unseen world for biologists but also established the field of microbiology. -
Robert Brown
Robert Brown, an English botanist, discovered the nucleus in plant cells. Matthias Jakob Schleiden, a German botanist, proposes that all plant tissues are composed of cells, and that cells are the basic building blocks of all plants. -
Matthias Schleiden
Matthias Jakob Schleiden, a German botanist, proposes that all plant tissues are composed of cells, and that cells are the basic building blocks of all plants. This statement was the first generalized statement about cells. -
Theodor Schwann
Theodor Schwann, a German botanist reached the conclusion that not only plants, but animal tissue as well is composed of cells. This ended debates that plants and animals were fundamentally different in structure. He also pulled together and organized previous statement on cells into one theory, which states: 1 - Cells are organisms and all organisms consist of one or more cells 2 - The cell is the basic unit of structure for all organisms -
Rudolf Virchow
Rudolf Virchow, a German physiologist/physician/pathologist added the 3rd part to the cell theory. The original is Greek, and states Omnis cellula e cellula. This translates as all cells develop only from existing cells. Virchow was also the first to propose that diseased cells come from healthy cells. -
