Woodhull, Alfred Alexander (1837-1921) U.S. army medical officer. Born in Princeton, New Jersey, Alfred Alexander Woodhull earned his M.D. from the University of Pennsylvania in 1859. He entered the Union Army Medical Department as an assistant surgeon in 1861, serving in that capacity throughout the conflict. After the war he published a number of pioneering works on hygiene and sanitation. His ideas were taught throughout the army, and helped inform the growing public health movement in the United States and its territories. He left the army in 1901 as a colonel, but was promoted to brigadier general on the retired list by Congress three years later.
