Andrzej Wiktor Schally, also known as Andrew W. Schally, (born november 20 1926) in Wilno, Poland), is a Polish-born endocrinologist and Nobel Prize winner in 1977 in Medicine for research work.

Although he was born in Poland, Andrew Schally had his formative education in Scotland and England. In 1952, he moved to Canada. He received his doctorate in endocrinology from McGill University in 1957. That same year he left for a research career in the United States where he has worked principally at Tulane University. A Canadian citizen when he left Canada, Schally became a naturalized citizen of the United States in 1962.

He developed a whole new realm of knowledge concerning the brain’s control over body chemistry. His works were also concentrated on birth control methods and growth hormones. He - as well as Roger Guillemin- described the neurohormone GnRH that controls FSH and LH. He was awarded an honorary Doctoral Degree from Jagiellonian University at Kraków.
