whom she met when they were both graduate students at the University of California, Berkeley. They were both hired by what was then the National Heart Institute in 1950 becoming the first husband-and-wife team at the National Institutes of Health. They both oversaw their own biochemistry labs and collaborated closely. In 2005, they were both honored by the NIH with an exhibit titled "The Stadtman Way: A Tale of Two Biochemists at NIH." Over a 60-year period, starting in 1943, she published 212 peer-reviewed papers. Stadtman was elected a member of the
