Biographical Note

Sarah Stewart (1906-1977) was born in Jalisco, Mexico. She received her M.S. from the University of Massachusetts (1930), her Ph.D. from the University of Chicago (1939), and her M.D. from Georgetown University (1949) and was its first female medical school graduate.

Primarily a microbiologist and bacteriologist, she first came to NIH in 1935. After a medical internship at the PHS Hospital in Staten Island, she returned to the National Cancer Institute in 1951, becoming Medical Director and Head of the Leukemia Studies Section. She became internationally known for her unique discovery that certain virus strains can jump species and produce cancers in other hosts. She also worked with Bernice Eddy to isolate and propagate the polyoma virus.

She left NIH in 1970 to become Professor of Pathology at Georgetown University.
