Albert Claude, known for Cell fractionation and Electron microscopy in biology, won a Nobel Prize in Physiology or Medicine in 1980.
In 1930 he developed the technique of cell fractionation, by which he discovered the agent of the Rous sarcoma, components of cell organelles such as mitochondrion, chloroplast, endoplasmic reticulum, Golgi apparatus, ribosome and lysosome. He was the first to employ the electron microscope in the field of biology. For his pioneering works he received the Louisa Gross Horwitz Prize in 1970, together with George Palade and Keith Porter, the Paul Ehrlich and Ludwig Darmstaedter Prize in 1971, and the Nobel Prize in Physiology or Medicine in 1974 with his student George Palade and friend Christian de Duve.
