Benjamin Spock
 was an American pediatrician, author, Olympic athlete, and political activist whose 1946 book The Common Sense Book of Baby and Child Care revolutionized parenting practices by promoting a flexible, child-centered approach that emphasized parental intuition, affection, and responsiveness over strict schedules and authoritarian discipline.[1][2] The volume sold over 50 million copies worldwide and was translated into dozens of languages, becoming a cornerstone reference for generations of parents.[2] As a member of the Yale University crew, Spock won a gold medal in the men's eight rowing event at the 1924 Paris Olympics.[3] In the 1960s, he emerged as a leading opponent of U.S. involvement in the Vietnam War, organizing protests, endorsing draft resistance, and facing federal conspiracy charges in 1968 for counseling evasion of military service—a conviction later reversed on appeal.[4][5] Spock ran for president in 1972 as the nominee of the People's Party, advocating socialist policies and immediate withdrawal from Vietnam, though he garnered fewer than 80,000 votes.[6] His permissive parenting tenets faced substantial backlash, with critics attributing rises in juvenile delinquency and cultural upheaval of the 1960s to diminished parental authority and overindulgence encouraged by his methods.[7]
