Guillemin, Roger

Guillemin, Roger (Charles Louis) (1924–  ) neuroendocrinologist; born in Dijon, France. He was an anti-Nazi resistance fighter in France during World War II, then received his M.D. from Lyons in 1949. He emigrated to the University of Montreal (1951–53), then came to the U.S.A. to join Baylor University (Texas) (1953–70). He collaborated with pioneer endocrinologist Andrew Schally on hypothalamic hormones which regulate the pituitary (1955–62), then continued independently at Baylor and the Salk Institute for Biological Studies (1970–89) where he isolated additional pituitary hormones and investigated the action of endorphins. For his many contributions to neuroendocrinology, Guillemin shared one-half the 1977 Nobel Prize in physiology with his former colleague Schally. He continued his work on brain chemistry and hypothalamic hormones at the Whitter Institute for Diabetes and Endocrinology, La Jolla (1989).
