Vivien Thomas

Vivien Theodore Thomas was an American laboratory supervisor who developed a procedure used to treat blue baby syndrome in the 1940s. He was the assistant to surgeon Alfred Blalock in Blalock's experimental animal laboratory at Vanderbilt University in Nashville, Tennessee, and later at the Johns Hopkins University in Baltimore, Maryland. He served as supervisor of the surgical laboratories at Johns Hopkins for 35 years. In 1976 Hopkins awarded him an honorary doctorate and named him an instructor of surgery for the Johns Hopkins School of Medicine. Without any education past high school, Thomas rose above poverty and racism to become a cardiac surgery pioneer and a teacher of operative techniques to many of the country's most prominent surgeons.
