Buffalo, New York and the Coris moved to Buffalo, New York. In 1928, they became naturalized citizens of the United States. While at the Institute the Coris’ research focused on carbohydrate metabolism, leading to the definition of the Cori cycle in 1929. In 1931, Carl accepted a position at the Washington University School of Medicine in St. Louis, Missouri. Carl joined as professor of pharmacology and in 1942 was made professor of biochemistry. In St. Louis, the Coris continued their research on glycogen and glucose and began to describe glycogenolysis, identifying and synthesizing the important enzyme glycogen phosphorylase. For these discoveries, they received the Nobel Prize in Physiology or Medicine in 1947, making them the third ever married couple to win the Nobel Prize. Gerty died in 1957 and Carl married Anne Fitzgerald-Jones (1909-2006) in 1960. He stayed on at Washington University until 1966, when he retired as chair of the biochemistry department. He was appointed visiting professor of Biological Chemistry at Harvard University while maintaining a laboratory space at the Massachusetts General Hospital, where he pursued research in genetics. From 1968 to 1983, he collaborated with noted geneticist Salomé Glüecksohn-Waelsch of the Albert Einstein College of Medicine in New York, until the 1980s when illness prevented him from continuing. In 1976, Carl received the Laurea honoris causa in Medicine from the University of Trieste. Carl shares a star with Gerty on the St. Louis Walk of Fame. Awards and honors In addition to winning the Nobel Prize, Cori won the Albert Lasker Award for Basic Medical Research in 1946 and in 1959, the Austrian Decoration for Science and Art. Cori was elected a Foreign Member of the Royal Society (ForMemRS) in 1950 and the Carl Cori Endowed Professorship at Washington University is named in his honor, currently held by Colin Nichols.
