Hooke is remembered for his contribution to microscopy. He invented the compound microscope which made it possible possible to observe cells. Van Leeunhoek is also remembered for his contributions to microscopy. His microscope had better lens than Hooke's, and he was able to see not only dead unmoving cells but microbes and sperms and other living cells. Based on observations enabled by the inventions of Hooke and Van Leeunhoek , Schleiden and Schwann were able to develop the theory that all living things are composed of cells--the Cell theory-- and that life only occurs in cells.
