Albert Claude, M. D. • M. D. degree from the Université de Liège, Belgium, in 1928 • For his discoveries concerning the structural and functional organization of cells, Claude received the 1974 Nobel Prize in Physiology or Medicine, which he shared with his student George Palade and Christian de Duve. • In 1930, Claude discovered the process of cell fractionation • While working at Rockefeller University in the 1930 s and 1940 s, he used the electron microscope to make images of cells which deepened the scientific understanding of cellular structure and function. He discovered the chloroplasts in the cell

Christian de Duve • • (1917— ) educated at the Catholic University of Louvain where he obtained his MD in 1941. 1974 Nobel Prize in Physiology or Medicine • discovered mitochondria, lysosome, peroxisome, endosome, etc

George Emil Palade, M. D. • • • 1974 Nobel Prize in Physiology or Medicine Romanian-born, 1912 AD. MD from the University of Bucharest, in 1946, began work at the Rockefeller Institute in New York. studies on the internal organization of such cell structures as mitochondria, chloroplasts, the Golgi apparatus, and others. His most important discovery was that microsomes, bodies formerly thought to be fragments of mitochondria, are actually parts of the endoplasmic reticulum (internal cellular transport system) and have a high ribonucleic acid (RNA) content. They were subsequently named ribosomes. became a professor of cytology at Rockefeller Institute, in 1958. In 1972 in cell biology at Yale University Medical School. In 1990 , the University of California, San Diego (UCSD) School of Medicine, where he acted as dean for scientific affairs, served as professor of medicine, and established an exceptional cell biology program. retired in 2001, becoming professor emeritus of medicine at UCSD.

Günter Blobel, M. D. , Ph. D. • The Nobel Prize in Physiology or Medicine 1999 • John D. Rockefeller, Jr. Professor; Investigator, HHMI Laboratory of Cell Biology • M. D. at Eberhard-Karl University of Tübingen, Germany, in 1960 • Ph. D. in oncology at the University of Wisconsin, 1967. • 1967, joined the Rockefeller University protein laboratory led by George Palade, • In 1976 became a professor at the university. • The unidirectional translocation of thousands of distinct proteins across specific intracellular membranes is mediated by "signal" sequences. • On average, a signal sequence consists of a stretch of ~15 amino acid
