Robert Hooke
Robert Hooke is the reason we named cells, "cells". In 1665, while looking at a cork, he saw little chambers that reminded him of a jail cell. The cells he looked at were dead plant cells. The reason they looked like jail cells because plant cells have a cell wall. The cell wall keeps the plant upright because plant don't have bones. -
Anton van Leeuwenhoek (Pond Water)
Anton van Leeuwenhoek was very interested in science. He built his own microscope and looked at everything with it. One of the things he looked at was pond water. While looking at the pond water, Anton van Leeuwenhoek discovered the first living cells. -
Anton van Leeuwenhoek (Teeth Gunk)
With the microscope he built, Anton van Leeuwenhoek looked at his teeth gunk in 1683. He discovered bacteria in his teeth gunk and thought they looked like animals. He called the little bacteria "animalcules". -
Robert Brown
Robert Brown was a Scottish botanist that had studies in medicine. In 1833 he discovered the nucleus in a plant cell. Robert Brown also made a discovery called the "Brownian Motion". He discovered this motion when he placed pollen in water and put it under a microscope. He noticed the pollen "jiggled" in the water. -
Felix Dujardin
Felix Dujardin is French biologist and was the first to group single-cell organisms. He discovered protozoa which is a single-celled animal the lives all over the world. He also concluded that all cells weren't hollow and were full of a jellylike material. -
Matthias Schleiden
Matthias Schleiden was one of the most important contributors to the cell theory. He was a botanist and loved to study plants. Using a microscope, he concluded that all plant are made of cells. Matthias Schleiden also worked with Theodor Schwann and Rudolph Virchow on the cell theory. -
Theodor Schwann
Theodor Schwann was a scientist that studied animals. After Matthias Schleiden concluded all plants are made of cells, Theodor Schwann concluded that all animals are made of cells too. This was a major contribution to the cell theory. He worked with Matthias Schleiden and Rudolph Virchow on the cell theory. -
Rudolph Virchow
Rudolph Virchow was another important contributor to the cell theory. He concluded that all cells come from other living cells. Rudolph Virchow also studied medicine and that was what helped lead him to his discovery. He also worked with Theodor Schwann and Matthias Schleiden on the cell theory.
