A red diaper baby is a child of parents who were members of the Communist Party USA (CPUSA) or the Communist Party of Canada, or were close to the party or sympathetic to its aims.
History
Gary Younge points out that the term "red diaper baby" originated in the 1920s as an insult. It was "aimed at the Communist party's internal aristocracy, which ensured that those with parents in the party would find themselves promoted rapidly through the party ranks". During the 1960s BerkeleyFree Speech Movement, the right-wing John Birch Society published a list of Berkeley student leaders, such as Bettina Aptheker, who were "red diaper babies". Instead of stigmatizing the named students, the disclosures had the opposite effect by helping them find one another and build a support network. In the years that followed, the term began appearing in popular culture without a pejorative connotation, e.g., in the 1976 film Marathon Man, the audience learns that the protagonist, Thomas Levy, played by Dustin Hoffman, is a red diaper baby.
In their 1998 book Red Diapers: Growing Up in the Communist Left, Judy Kaplan and Linn Shapiro define red diaper babies as "children of CPUSA members, children of former CPUSA members, and children whose parents never became members of the CPUSA but were involved in political, cultural, or educational activities led or supported by the Party". More generally, the term is sometimes used to refer to a child of any radical parent, regardless of that parent's party affiliations. Shapiro writes that red diaper babies commonly reported "growing up with a sense of difference, both specialness and fear; feeling part of an international community and yet isolated from the mainstream of their own country." She adds that as adults, they "may or may not be political activists. Within families, siblings often differ in type and degree of activism and impact of the 'red diaper' experience on their lives."
