Olga Bianchi Droguett (1924–2015) was an Argentine-born Chilean filmmaker, feminist, pacifist and women's rights activist. As a result of her resistance to Augusto Pinochet, she fled Chile in 1975 and settled with her children in Costa Rica. A convinced pacifist, in the early 1980s she joined Liga Internacional de las Mujeres Pro Paz y Libertad (LIMPAL), the Latin American branch of the Women's International League for Peace and Freedom (WILPF), becoming LIMPAL vice-president in 1986 and 1989. In addition, she served as LIMPAL's permanent representative to the United Nations in Geneva. Bianchi was also a board member of Amnesty International in Costa Rica and a founding member of the human rights organization CODEHU, the Costa Rican representation with the United Nations Commission on Human Rights.[1][2][3]
