Roger I. Lee was head of the Department of Hygiene. As doctor to the students, he conducted their annual physical examinations. He was born in 1881 and at Harvard he earned his bachelor's degree in 1902 and medical degree in 1905. He served as a lieutenant colonel in the Medical Corps in World War I. Upon his return from service he authored "Health and Disease: Their Determining Factors". As a reaction to the discovery that so many World War I recruits were unfit for service, he initiated at Harvard one of the first collegiate fitness programs in 1919. He was a professor of hygiene from 1914 to 1924 and later served as a member of the Harvard Corporation from 1931 to 1954. He played a prominent role in several medical organizations, notably as President of the American Medical Association in 1945-46. He retired from the practice of medicine at 80 and died October 29, 1965, at the age of 84.
