Isabel Martínez de Perón
María Estela Martínez Cartas de Perón (born 4 February 1931), better known as Isabel Martínez de Perón () or Isabel Perón, served as the 42nd President of Argentina from 1974 to 1976. She was the third wife of President Juan Perón. During her husband's third term as president from 1973 to 1974, Isabel served as both vice president and First Lady. Following her husband's death in office in 1974, Isabel served as president of Argentina from 1 July 1974 to 24 March 1976, when the military took over the government and placed her under house arrest for five years, before exiling her to Spain in 1981. She holds the distinction of having been the first woman to have had the title of "President", as opposed to a queen or prime minister.
María Jesús Alvarado Rivera
After returning from exile, she devoted her time to radio, theater and cinema, with the primary purpose of getting voting rights for women in Peru. She also wrote a play, "The Perricholi", that was aired by Radio Nacional del Perú. She established the Academy of Dramatic Arts, "Ollanta", with her own money which found acceptance by the Ministry of Education as it helped to create the Directorate of Cultural and Art in Peru. In 1938, she mooted the introduction of the "Code of Rights" for women, in 1940, she wrote on the topic of "Eugenics and Child" in "Semana de la Salud". In 1945, the government approved her proposal to establish the national theater. She also became the Councillor of the Municipality of Lima.
The feminist movement launched by Alvarado Rivera took a long time to take shape, and it was only in 1955 that women got the right to vote in Peru. She died on May 6, 1971, at 92 years of age, a much disappointed woman as her efforts in the feminist movement did not get her acclaim during her lifetime.
