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.
In 1975, faced with political detention for distributing films on human rights and democracy, she was forced to leave Chile, soon settling in Costa Rica with her small children.
[1][2] Increasingly intent on supporting pacifism, in 1983 Bianchi first joined the Centro de Amigos para la Paz (CAP), a peace centre in San José newly established by the quakers.
[2][5] She then went on to become a member of the closely related Liga Internacional Por Paz y Libertad (LIMPAL), established in Costa Rica as the Latin American branch of the WILPF, serving as the organization's international vice-president in 1986 and 1989.
