About Roger Guillemin
Roger Charles Louis Guillemin (French pronunciation: [ʁɔʒe ʃaʁl lwi ɡijmɛ̃]; January 11, 1924 – February 21, 2024) was a French-American neuroscientist. He received the National Medal of Science in 1976, and the Nobel Prize for Medicine in 1977 for his work on neurohormones, sharing the prize that year with Andrew Schally and Rosalyn Sussman Yalow. Guillemin and Schally discovered the structures of Thyrotropin-releasing hormone (TRH) and Gonadotropin-releasing hormone (GnRH) in separate laboratories. They were awarded the 1977 Nobel Prize in Physiology or Medicine for this discovery. Here, he discovered somatostatin, and was "among the first" to isolate endorphins. Guillemin protege, Wylie Vale Jr., established his own laboratory at Salk in 1977; their attempts of finding releasing factors was described as "yet another furious rivalry"; Vale's lab was first to purify and sequence the CRF.
