The document discusses the development of cell theory and the scientists who contributed to it. Anton van Leeuwenhoek invented the compound microscope and was the first to observe cells. Robert Hooke coined the term "cell" after observing cork cells. Matthias Schlieden and Theodor Schwann discovered that plants and animals are made of cells, respectively. Rudolf Virchow established that cells only come from pre-existing cells, which became a tenet of cell theory along with cells being the basic unit of structure and function. Francesco Redi and Louis Pasteur also made discoveries that supported the germ theory of disease.
