Benjamin Spock

Benjamin McLane Spock (May 2, 1903–March 15, 1998), widely known as Dr. Spock, was an American pediatrician, Olympian athlete and left-wing political activist. His book Baby and Child Care (1946) is one of the best-selling books of the 20th century, selling 500,000 copies in the six months after its initial publication and 50 million by the time of Spock's death in 1998. The book's premise told mothers, "You know more than you think you do." Dr. Spock was widely regarded as a trusted source for parenting advice in his generation.

Spock was the first pediatrician to study psychoanalysis in an effort to understand children's needs and family dynamics. His ideas influenced several generations of parents, encouraging them to be more flexible and affectionate with their children and to treat them as individuals. However, his theories were widely criticized by colleagues for relying heavily on anecdotal evidence rather than serious academic research.

After undergoing a self-described "conversion to socialism," Spock became an activist in the New Left and anti-Vietnam War movements during the 1960s and early 1970s, culminating in his run for President of the United States as the People's Party nominee in 1972. He campaigned on a maximum wage, legalized abortion, and withdrawing troops from all foreign countries. His books were criticized by conservatives for propagating permissiveness and an expectation of instant gratification, a charge that Spock denied.
