Gladys Dick
Gladys Rowena Henry Dick was an American physician who codeveloped a vaccine for scarlet fever with her husband, George F. Dick.
Gladys Rowena Henry was born in Pawnee City, Nebraska in 1881 and earned her B.S. in zoology from the University of NebraskaLincoln in 1900. Because her mother initially objected to Gladys attending medical school, she took graduate classes at Nebraska until 1903, then moved to Baltimore to attend Johns Hopkins University School of Medicine. She graduated in 1907 with her M.D. then trained for a year at the University of Berlin. Dicks years at Johns Hopkins and Berlin marked her introduction to biomedical research and provided opportunities to study experimental cardiac surgery and blood chemistry with Harvey Cushing, W.G. MacCallum, and Milton Winternitz.
