Gerty Cori

Gerty Theresa Cori (née Radnitz; August 15, 1896 – October 26, 1957) was an Austrian-born American biochemist renowned for her pioneering research on carbohydrate metabolism. Born in Prague to a Jewish family, she earned her medical degree from the German University of Prague in 1920 and married fellow student Carl Ferdinand Cori, with whom she collaborated throughout her career. Facing antisemitism in post-World War I Europe, the couple emigrated to the United States in 1922, where they conducted groundbreaking experiments at the State Institute for the Study of Malignant Disease in Buffalo and later at Washington University School of Medicine in St. Louis. In 1929, the Coris discovered the metabolic pathway now known as the Cori cycle, which describes how lactate produced by anaerobic glycolysis in muscles is transported to the liver, converted to glucose, and returned to muscles for glycogen resynthesis, providing critical insights into energy utilization in the body. Their elucidation of the enzymatic processes involved in glycogen breakdown and synthesis, including the isolation of glucose-1-phosphate and phosphorylase, earned them shared the 1947 Nobel Prize in Physiology or Medicine with Bernardo Houssay, marking Cori as the first American woman to win a Nobel Prize in science. Despite institutional barriers as a woman in academia, her work laid foundational principles for understanding metabolic disorders like diabetes and advanced treatments for glycogen storage diseases.

Gerty Theresa Radnitz was born on August 15, 1896, in Prague, then part of the Austro-Hungarian Empire, to an upper-middle-class Jewish family. She was the eldest of three daughters born to Otto Radnitz, a chemist who managed sugar refineries after developing a successful method for refining sugar, and Martha Neustadt, whose brother was a professor of pediatrics.

Gerty's early childhood education occurred at home under private tutors, reflecting the family's socioeconomic status and cultural emphasis on intellectual development within Prague's Jewish community. In 1906, at age ten, she entered a lyceum for girls, where her academic aptitude became evident.
