Thomas Francis, Jr., was the thirty-third president of the American Association of Immunologists, serving from 1949 to 1950. He was the Henry Sewall University Professor and chairman of the Department of Epidemiology of the University of Michigan School of Public Health from 1941 to 1969. Francis gained renown for his studies on influenza during the 1930s and 1940s, and, in 1954, he oversaw the trials of the polio vaccine developed by his former research fellow Jonas Salk (AAI ’47) and colleagues at the University of Pittsburgh.
Francis received his M.D. from the Yale University School of Medicine in 1925 and completed a two-year residency at the New Haven Hospital under Francis G. Blake (AAI ’21, president 1934–1935). Blake, who also chaired the Department of Internal Medicine at Yale, hired Francis as an instructor in 1927. The following year, Francis became an assistant at the Rockefeller Institute Hospital, where he was mentored by Rufus Cole (AAI ’17, president 1920–1921). After rising to the rank of associate in 1931, Francis left the hospital in 1936 to join the staff of the International Health Division of the Rockefeller Foundation. Two years later, he was appointed professor of bacteriology and director of the Bacteriological Laboratories at the New York University College of Medicine, a position he held until he joined the faculty of the University of Michigan School of Public Health in 1941.
