Renée Slotopolsky de Epelbaum

Renée Slotopolsky de Epelbaum (June 15, 1920 – February 7, 1998), also known as Yoyi Epelbaum, was an Argentine human rights activist. She is known for being one of the founders of the Mothers of the Plaza de Mayo, an association of mothers of those disappeared during the military dictatorship known as National Reorganization Process that ruled Argentina between 1976 and 1983. She was also one of the founders of the Jewish movement for Human Rights (Spanish: Movimiento Judío por los Derechos Humanos).

One of her sons, Luis Marcelo (25), medical student, was kidnapped on August 10, 1976 in Buenos Aires as he left the university. Claudio (23), a law student and Lila (20), dancer, were sent home holiday in Uruguay, in the city of Punta del Este where they thought they would be safe. However, Argentine squads in cooperation with the Uruguayan regime followed them, being kidnapped on November 4, 1976.
