Barbara Zeluck (1923-2010) along with her husband Steve Zeluck (1922-1985) were Trotskyists, and labor union, and occupational health activists. Barbara Zeluck was involved in socialist feminist and women's health care activism. Former members of the Socialist Workers Party, the Zelucks were also involved in the "Regroupment" efforts of the late 1970s-early 1980s to bring together several Trotskyist organizations. They left the SWP, and were successively involved in the Trotskyist groups International Socialists, Workers Power, and Solidarity.
