Janssen
Hans and Zacharias Janssen were the inventors of the first compound microscope. -
Hooke
English physicist Robert Hooke looked at a sliver of cork through a microscope lens and noticed some "pores" or "cells" in it. He believed the cells had served as containers for the "fibrous threads" of the once-living cork tree. Hooke was the first person to use the word "cell" to identify microscopic structures when he was describing cork. It was the spark of cell theory. -
Redi
He did an experiment to determine if rotting meat turned into flies. He found that meat cannot turn into flies and only flies could make more flies. This was an important experiment because it helped to disprove the theory of spontaneous generation. It did this by showing that the rotten meat did not turn into flies and only flies could make more flies. -
Antonio Van Leeuwenhoek
Anton Van Leeuwenhoek was the first to see and describe bacteria. -
Abraham Trembley
Watched cells replicate. -
Wolff
Proposed a general cell theory -
Henri Dutrochet
Discovered cell biology and cells in plants. -
Fancois Vincent Raspail
Raspail was one of the founders of the cell theory in biology. He coined the phrase omnis cellula e cellula ("every cell is derived from a [preexisting] cell") He was an early proponent of the use of the microscope in the study of plants. -
Turpin
Observed cell division. -
Franz Meyen
He wrote the Phytotomie the first review of plant anatomy. -
Brown
Robert Brown discovered the cell nucleus. -
Robert Remack
Discovered the origin of cells by division of pre-exsisting cells. -
Schwann
Schwann proposed that all organisms are composed of cells. Together with Matthias Schleiden he formulated the cell theory of life. Schwann also discovered the cells, now known as Schwann cells, that form a sheath surrounding nerve axons and conducted experiments that helped disprove the theory of spontaneous generation. -
Schleiden
Theodor Schwann and Matthias Jakob Schleiden created what is called the cell theory. The cell theory states that all living things are made up of one or more cells. -
Virchow
Rudolf Virchow published his now-famous aphorism omnis cellula e cellula ("every cell stems from another cell"). He also stated that all diseases involve changes in normal cells. -
Mendel
Began experiments with pea plants. Became known as "Father of Genetics" -
Pasteur
Louis Pasteur did an experiment that determined that soup exposed to air only spoiled if the air was not filtered or if the flask containing the soup had an opening that allowed micro organisms to get to the soup. If he used flasks with long S-shaped necks the micro organisms that spoiled the soup settled in the neck and did not spoil the soup. -
Hugo von Mohl
First came up with the word Protoplasm. -
Camillo Golgi
Discovered and named the golgi body. -
Schnieder
He published the first paper containing a description of the proccess of cell division and divisible changes during its successive stages.
