Caroline B. Thomas
by Mary Lewis Carey
oil on canvas, 28 by 24 inches, 1951


Caroline B. Thomas was born in Ithaca, New York. She received her B.A. in 1925 from Smith College, then did graduate work in general physiology and genetics at the Johns Hopkins University under Herbert S. Jennings in the department of biology. Eventually, she entered the Johns Hopkins University School of Medicine, receiving her M.D. in 1930. Thomas conducted research in electrocardiography at the school of medicine during her residency at the hospital from 1931 until 1933, when she was named a National Research Council fellow in medicine and a fellow in neuropathology at Harvard University.

She returned to Johns Hopkins in 1934 as a fellow in physiology, and in 1935 she joined the faculty of the school of medicine. She was appointed associate professor in 1952 and professor emeritus in 1970. Thomas held a variety of staff appointments at the Johns Hopkins Hospital and also served on the faculty of the school of hygiene and public health. In 1946, she began a long-term study entitled "The Precursors of Essential Hypertension and Coronary Artery Disease." The subjects enrolled in the study when they were Johns Hopkins medical students and were regularly followed throughout their lives. Thomas published several books from this study, showing the influence of personality and daily habits as factors in the prediction of heart disease, suicide, cancer, and longevity.
