Guillemin, Roger Charles Louis, 1924-, French-American physiologist, b. Dijon, France. Educated in France, he fought for the resistance during World War II. He taught primarily at Baylor Univ. (1953-70), until he became a researcher at the Salk Institute for Biological Studies (Calif.). Guillemin isolated and synthesized the hormones produced by the hypothalamus gland. These hormones regulate the pituitary gland, which governs other glands that regulate such body functions as reproduction and emotional responses. He also discovered endorphins, a class of hormonal substances. His work added new dimensions to the study of the brain's control over the body's chemistry. In 1977, Guillemin shared the Nobel Prize in Physiology or Medicine with Andrew Schally and Rosalyn Yalow.

Biography

Born in Paris, the eldest son of Victor-François, 2nd duc de Broglie, the prince de Broglie attained the rank of maréchal de camp in the army. He adopted revolutionary opinions, served with the Marquis de La Fayette and the Comte de Rochambeau in the American Revolutionary War,

The Prince was a member of the Jacobin Club, and sat in the National Constituent Assembly after the French Revolution, constantly voting on the Liberal side. He served as chief of the staff to the First Republic's Army on the Rhine, but, during the Reign of Terror, he was denounced, arrested, and guillotined in Paris.

Since the old duc de Broglie survived him, the prince de Broglie's eldest son, Victor, eventually became the third duc de Broglie. The prince's dying admonition to his little son was to remain faithful to the principles of the Revolution, however unjust and ungrateful it seemed then to be.
