Robert Hooke
Robert Hooke contributed to the cell theory by introducing the world to "cells". His discovery was made by observing a thin cutting of cork and finding walls with empty space, he named these spaces "cells." Hooke calculated the number of cells in a cubic inch to be 1,259,712. -
Anton Van Leeuwenhoek
Leeuwenhoek contributed to the cell theory unicellular bacteria in 1674. Leeuwenhoek improved the microscope so that he was able to magnify with much better resolution than Hooke, which encouraged his discovery. Single-celled organisms was discovered when Leeuwenhoek examined pond water through a microscope and saw dozens of protists, which he named "animalcules." -
Henri Dutrochet
Dutrochet's theory states "...everything is ultimately derived from the cell." His discovery was made when he noticed the similarity of chemical and physical components in plants and animals. He then curved his focus specifically towards plants and animals. This improved previous theories by disproving the idea of spontaneous generation. -
Felix Dujardin
Dujardin's contributed to the cell theory by discovering that many living organisms are composed of a single cell. He came to this conclusion after having many observations through a microscope. His discovery paved the way for future cell discoveries such as Schwann and Schleiden -
Matthias Schleiden
Schleiden's discovery that all plants are composed of cells was made in 1838. He was a highly accepted botanists, so his discovery was encouraged by his interest in plants. -
Theodor Schwann
Schwann's theory stating that all living things are composed of cells was made when he extended Schleiden's experiment to animals. This disproved previous theories, such as Schleiden and Dujardin, that says plants and animals have different compostitions -
Rudolf Virchow
Virchow contribution to the cell theory was his discovery that all living things come from other living things.Virchow's discovery was made when he took part in an experiment classifying diseases.
