Born on 24 March 1890 in Marlborough, Massachusetts, to Ann and Frank Rock, John Charles Rock was both a devout Catholic and one of the leading investigators involved in the development of the first oral contraceptive pill. In 1925 he married Anna Thorndike, with whom he later had five children. He spent over thirty years of his career as a clinical professor of obstetrics at Harvard Medical School, and in 1964 the Center for Population Studies of the Harvard School of Public Health established the John Rock Professorship. As a member of the Catholic Church, his faith played an intriguing role in his involvement with the development of the birth control pill, which challenged previous Catholic thought on contraception. Rock's unique position as a Catholic, a physician, and researcher of human reproduction sparked both interest and controversy within the Church as well as popular society more generally, with Life, Time, and Newsweek magazines all devoting feature articles to Rock.
