José López Rega (17 November 1916 – 9 June 1989) was an Argentine politician who served as Minister of Social Welfare from 1973 to 1975, first under Juan Perón and continuing under Isabel Perón, Juan Perón's third wife and presidential successor. Lopez Rega exercised Rasputin-like authority over Isabel Perón during her presidency, and used his influence and unique access to become the de facto ruler of Argentina. His far-right politics and interest in the occult earned him the nickname El Brujo ("the Warlock"). Rega had one daughter, Norma Beatriz, who went on to become the spouse of President Raúl Lastiri.
