Andrzej Viktor "Andrew" Schally (30 November 1926 – 17 October 2024) was a Polish-American endocrinologist who was a co-recipient, with Roger Guillemin and Rosalyn Sussman Yalow, of the 1977 Nobel Prize in Physiology or Medicine.

[5] Later in life, Schally utilized his knowledge of hypothalamic hormones to research possible methods for birth control and cancer treatment.

I used to speak Polish, Roumanian, Yiddish, Italian and some German and Russian, but I have almost completely forgotten them, and my French in which I used to excel is also now far from fluent.

[9][10] In 1981, it was demonstrated that the gonadotropin-releasing hormone (GnRH) agonistic analogs that Schally had developed between the years of 1972 and 1978 inhibited the growth of prostate cancer in rats.

Alongside Dr. George Tolis, Schally conducted the first clinical trial of GnRH for patients with advanced prostate cancer in 1982.

[7] The previous method of treatment, orchiectomy or the administration of estrogens, was based on the research of Charles Brenton Huggins.
