Biography

Early life and education

Sarah Elizabeth Stewart was born on August 16, 1905 in Tecalitlán, Jalisco, Mexico.[1] Born to a Mexican mother and American engineer father, she moved back to the United States at the age of 5.[2] She did her undergraduate work at the New Mexico State University, graduating with a Bachelor of Science in 1927. She went on to earn a master's degree from the University of Massachusetts Amherst in 1930 and a Ph.D in microbiology from the University of Chicago in 1939. In 1949, she became the first woman to be awarded an MD Degree from Georgetown University School of Medicine.[3]

Career

Stewart joined the National Institutes of Health (NIH) from 1935-1944 while completing her PhD at the University of Chicago.[2] She went on to teach microbiology at Georgetown University's School of Medicine, and once women were allowed to enroll, she became their first female graduate at the age of 39.[2][4] Stewart returned to the NIH in 1951, joining the National Cancer Institute (NCI), and eventually becoming medical director.[2]

Stewart developed an interest in researching viral links to cancer in light of the pioneering research of Jonas Salk in developing a vaccine for the virus which caused polio. Stewart is credited with discovering the Polyomavirus in 1953.[3] She and research partner, Dr. Bernice E. Eddy, were successful in growing the virus in 1958 and the SE (Stewart-Eddy) polyoma virus is named after them. Stewart was the first to successfully demonstrate that viruses causing cancer could be spread from animal to animal.[5]

She left the NIH to become professor at Georgetown University in 1971.[4]

Death and afterward

Stewart died of cancer at her home in New Smyrna Beach, Florida on November 27, 1976.[6] A collection of her papers is held at the National Library of Medicine in Bethesda, Maryland.[7]
