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.
Ana Fidelia Quirot
One of her most impressive career stats is a perfect 4-0 record against the great Maria Mutola, widely considered the greatest 800 metre runner in history, in World and Olympic competition. She cracked the 1:55 barrier on 2 occasions, and was the only female to break 1:55 between over a 25-year span from 1983 (Kratochvílová) to 2008 (Jelimo). She is one of a handful of women to ever be ranked No. 1 in the world in both 400 and 800 metres in the same year, a feat she achieved in her career year of 1989, when she was named IAAF track athlete of the year by the prestigious Track and Field News Magazine. She was quite possibly denied her elusive Olympic Gold in the 800 metres in 1988, and a medal in the 400 metres, had it not been for the boycott, as she was unbeaten in the 800 metres all year, and a world leader in the 400 metres.
