Dr. Clarence J. Gamble was elected president by the board of directors of the newly incorporated Pathfinder Fund on February 27, 1957. But the work of The Pathfinder Fund to make birth control available began some 28 years earlier, in 1929, when Clarence Gamble gave $5,000 to open a maternal health clinic in Cincinnati, Ohio. Along with Margaret Sanger, working in projects since The Negro Project, and Robert Latou Dickinson, he spearheaded the movement to gain acceptance for birth control in the United States.
