Jorge Sigal was born in San Juan, Argentina, in 1953. At the age of 8, in Turdera –Buenos Aires–, where his family had settled, he carried out his first revolutionary action: with his cousin Héctor he forged an Argentine Communist Party card. At seventeen he traveled to Moscow to study Marxism-Leninism at an institute dependent on the Central Committee of the Union of Communist Youth of the USSR (Komsomol). In 1984, when he was a member of the Executive Committee of the CP youth organization, he renounced his party affiliation and ventured into professional journalism. He was a collaborator of La Razón and El Periodista de Buenos Aires; editor of Semana Gráfica, Acción and Somos; director of the APDH monthly; editorial secretary of People; editor of Página/12 and Perfil and editor-in-chief of the magazine 3 Puntos. He was editorial director of the Capital Intelectual label. In 2014 and 2015 he served as a current affairs analyst on Fernando Bravo's program on Radio Continental and was a member of the Board of Directors of the Argentine Political Club. From December 2015 to October 2018 he was Secretary of Public Media of the Argentine government. He writes in the Opinion section of the newspaper La Nación.
