Biography
Born in Buenos Aires on 3 January 1912, Corina Eloísa Ratto was the daughter of Livio Benito Ratto and Francisca Butta. Brought up in a middle-class family of Italian origin, in the 1930s she graduated in mathematics from the University of Buenos Aires. After Juan Perón had been overthrown, she was able to complete her doctorate under Mischa Cotlar in 1959 with her thesis Conditions of Continuity of Generalized Potential Operators with Hyperbolic Metric. While a student in the 1930s, she played a major role in the Argentine student organizationFederación Universitaria Argentina. She supported republican interests during the Spanish Civil War and helped victims of Falangist oppression. She denounced the Chaco War on the grounds that it had been triggered by British and American interests. In 1937, she married the mathematician Manuel Sadosky with whom she had one child, Cora Sadosky, who also became a prominent mathematician and was president of the Association for Women in Mathematics in the mid-1990s. After the Nazis invaded the Soviet Union in World War II, in the early 1940s Ratto established and headed the women's organizationLa Junta de la Victoria to promote democracy and provide support for the anti-Nazi war effort, including clothing ánd food for the Allies. By 1945, it had some 50,000 members, making it the first significant women's organization in South America. The organization also served to encourage its members to fight for votes for women. After the war, the family moved to Europe where Ratto and her husband furthered their studies in France and Italy. Thereafter they returned to Argentina which was in political turmoil. Ratto worked in a commercial firm to sustain the family. Only in 1956, when the universities regained independence, did the couple take up positions at the University of Buenos Aires. In 1965, Ratto founded Columna 10, a journal denouncing the conduct of the United States in the Vietnam War. In the 1970s, she published a series of important mathematics text books in Spanish, including Introducción al álgebra: nociones de álgebra lineal and Material formativo para docentes de matemática del nivel secundario. Threatened by the anti-communist organization Alianza Anticomunista Argentina, Ratto left Argentina in 1974, first moving to Venezuela, then to Spain. She died in Barcelona in 2 January 1981.
