Gerty Theresa Cori, née Radnitz, (August 15, 1896 - October 26, 1957) was an American biochemist born in Prague (then Austria-Hungary) who, together with her husband Carl Ferdinand Cori and Argentine physiologist Bernardo Houssay, received a Nobel prize in 1947 for their discovery of how glycogen (animal starch) - a derivative of glucose - is broken down and resynthesized in the body, for use as a store and source of energy.
In 1914, she started medicine at Charles University in Prague, where she met Carl Cori. After graduation, she converted to Catholicism so she could marry Carl in church. In 1921, she started working in a hospital in Vienna, but followed her husband to Buffalo, New York the next year.
