Hooke
Hooke was the first to describe cells. Hooke did this my making thin slices of cork and calling them cells. He never said that the cell was the basic unit of life. hooke also believed that the spaces in the cells could be for transfer of liquids. Hooke wrote the book ,Micrographiaon, 60 observations that he found under his microscope. -

leeuwenhoek
Leeuwenhoek proved that unicellular organisms exsisted. This was proved by his powerful microscopes, more powerful than Hooke's. Leeuwenhoek is the father of microbiology. This disproved Hooke, who thought that single cells have no life. His discovery of bacteria, first found living one celled orginism, was found by using water outside his house and putting his findings under his powerful course microscope. -
Dutrochet
First to declare that cells are the basic orginization of life, but it wasn't until Schwann and Schleiden that the cell theory was made. This changed the thought of everyone that made contribution leading up to this ,because none were to state that cells orginized life, only that cells were nonliving or unicelluler. -
Dujardin
Dujardin found that many living orginisms are made of a single cell. He also found that all cells are similar internally. Dujaardin was also the first to state that cells weren't hollow. This changed what dutrochet stated that cells were the basic unit of all life. -
Schleiden
Schleiden concluded that every plant is made up of cells; that the cell is the basic unit of plant life. This disproved all other models because no other model exclaimed the magnitude of cells in the terms of life. The closest to this model was Leeuwenhoek who found unicelluar life. This disproved the pre-exsisting theory that most orginisms are unicellular. -
Schwann
Followed up on what Schleiden started. Schleiden, Schwann's scientific predesesor of the cell theory, claimed plants were made of cells, but Schwann discovered that animals were too, made of cells. Schwannwent further and stated that all orginisms consist of one or more cells; cells are the basic unit of life. These statements are what became known as the first tenets of Cell Theory. This dispproved Schawann saying that only plants are made of cells and unicellular orginisms. -
Virchow
In 1855, Virchow stated new cells can only come from the splitting of a living cell (third tenet of cell theory). VIrchow was also the first to show that not only does the cell theory apply to healthy cells, but also diseased cells. This disproved everyone by saying cells could also be diseased and follow the cell theory. All other research done before Virchow was on healthy cells.
