Andrzej Wiktor Schally (also known as Andrew W. Schally; November 30, 1926 – October 17, 2024) was a Polish-born Americanendocrinologist. In 1977, He won the Nobel Prize in Physiology or Medicine. While he lived in a Jewish community and subsequently fled Poland, a genealogical investigation cited in the footnotes of JINFO.org found that Schally's background was "predominantly Polish, and not Jewish".
He developed a whole new realm of knowledge concerning the brain’s control over the body chemistry. His works also addressed birth control methods and growth hormones. He - as well as Roger Guillemin- described the neurohormoneGnRH that controls FSH and LH. He was awarded an honorary Doctoral Degree from Jagiellonian University at Kraków.
