Roger Guillemin
French-American neuroscientist (1924–2024)
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.
Biography
Guillemin was born in Dijon, France. After secondary studies at the Lycée Carnot in Dijon, he began his medical studies at the University of Dijon in 1943. He completed his medical studies at the University of Lyon and received MD degree in 1949. He worked as a doctor in a small village in Burgundy, and went to Montreal, Quebec, Canada, to work with Hans Selye at the Institute of Experimental Medicine and Surgery at the Université de Montréal where he received a Ph.D. in 1953. In 1965, he became a naturalized citizen of the United States.
In 1954, Guillemin observed that pituitary cells do not produce hormones unless hypothalamic cells are present, which supported the theory that the hypothalamus controls the pituitary through hormones, dubbed releasing factors. Guillemin moved to Baylor College of Medicine, in Houston, to develop that finding. Andrzej V. Schally, known in the US as Andrew Schally, joined him in 1957.

Why this record matters
The phrase “french-American neuroscientist (1924–2024)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q242169. VIAF identifies the subject as 109127804. The Library of Congress control number is n84125927. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1924, 2024, 1976 and 1977.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
