José López Rega
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 an allegedly Rasputin-like power and influence over Isabel Perón during her presidency, and used both this and his unique access to become the de facto political boss of Argentina.
