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.
Estela Quesada
She returned to Alajuela and began studying law at the University of Costa Rica, while simultaneously teaching at the Escuela León Vargas. In the late 1940s, she participated in the push for the right to vote for women and when it successfully passed in 1949, she began to look at politics. In 1950, she was promoted to serve as president of the National Education Association (ANDE). 1953 was a landmark year for Quesada, as she finished her law degree and won one of the first three seats ever awarded to a woman in the Costa Rican legislature. She earned the title of vice president of the legislature, and in 1957 became the first woman in the country's history to lead the work of parliament. When Mario Echandi Jiménez was elected president, he appointed Quesada as the first Minister in the country's history. As Minister of Education, she instituted a merit based system for teacher hirings, removed dress codes which were costly, improved public education and specifically focused on improving rural education completion rates.
