Robert Hooke
Robert Hooke discovered the cell approximately in 1665. In cork, he discovered the organization of cells and introduced the word CELL to science. Hooke looked through a microscope that was 50x the magnification and saw little spaces in between a piece of cork he was looking at. -
Francesco Redi
An Italian physician, Francesco Redi, performed an experiment to see if rotting meat changed into flies. He discovered that only flies to could make more flies, thus disproving the theory of spontaneous generation. -
Antonie van Leeuwenhoek
Leeuwenhoek discovered microorganisms approximately in 1674 while looking through a microscope examining pond water. He called them animaculus. Leeuwenhoek also redefined the microscope with the magnification increasing to at least 270x. -
Robert Brown
Robert Brown discovers the nucleus of the cell. He stresses its importance in fertilisation. -
Mathias Jacob Schleiden
He observed that all plants are made of cells. -
Thomas Schwann
He observed that all animals are made of cells. Talking to Schleiden, they realized that all living things are made of cells -
Jan Evangelista Purkinje
He discovered the microtome to cut thin slices of material to watch it in the microscope. He described cerebellum neurons -
Gregor Mendel
He described the Hereditary Factors as the responsible of the transmission of hereditary traits -
Louis Pasteur
He demonstrated that microorganisms did not appear by spontaneous generation, but by the division of previous cells. -
Friedrich Miescher
He isolated a non-proteinic substance from the nucleus of pus cells that happened to be DNA. He called it nuclein -
Sutton and Boveri
They introduce the idea of genes as the structures that carry genetic information -
Santiago Ramón y Cajal
He is the father of neuroscience. He described the way neurons transmit the nerve impulses (synapse). He was awarded with the Nobel price -
Thomas Morgan
He discovered that genes are located in the chromosomes -
Rosalind Franklin
She worked with X-rays, taking pictures to DNA molecules. She made the picture 51, on which Watson and Crick based the description of the DNA molecule structure -
Watson and Crick
They established the molecular structure of the DNA and indicated how it will copy itself -
Lynn Margulis
She set the endosymbiotic theory that describes the origin of eukaryotic cells as the result of a symbiosis with prokaryotic cells
