William G. MacCallum was born in Dunnville, Ontario. He received a B.A from the University of Toronto in 1894. A member of the first graduating class of the Johns Hopkins University School of Medicine, he received his M.D. in 1897. He joined the Johns Hopkins medical faculty in 1898 after spending one year as a resident house officer at the Johns Hopkins Hospital. From 1909 to 1917, he was professor of pathology at the College of Physicians and Surgeons of Columbia University. He then returned to Johns Hopkins as professor and chairman of the department of pathology, a position he held until his retirement in 1943. His research covered a wide variety of subjects; his most notable contributions were those relating to malaria and the function of the parathyroid gland. He traveled extensively and used his trips to broaden his knowledge of pathological anatomy. He wrote the definitive Textbook of Pathology and 173 articles, as well as biographical sketches and studies in the history of medicine.
