Alexander Grothendieck
Alexander Grothendieck (German: [ˈɡroːtn̩diːk]; French: [ɡʁɔtɛndik]; 28 March 1928 – 13 November 2014) was a German-born French mathematician who became the leading figure in the creation of modern algebraic geometry. His research extended the scope of the field and added elements of commutative algebra, homological algebra, sheaf theory and category theory to its foundations, while his so-called ""relative"" perspective led to revolutionary advances in many areas of pure mathematics.Born in Germany, Grothendieck was raised and lived primarily in France. For much of his working life, however, he was, in effect, stateless. As he consistently spelled his first name ""Alexander"" rather than ""Alexandre"" and his surname, taken from his mother, was the Dutch-like Low German ""Grothendieck,"" he was sometimes mistakenly believed to be of Dutch origin.Grothendieck began his very productive and public career as a mathematician in 1949. In 1958, he was appointed a research professor at the Institut des hautes études scientifiques (IHÉS) and remained there until 1970, when, driven by personal and political convictions, he left following a dispute over military funding. Although he later became a professor at the University of Montpellier and produced some private mathematical work, he otherwise withdrew from the mathematical community and devoted himself to political causes. Soon after his formal retirement in 1988, he moved to the Pyrenees, where he lived in isolation until his death in 2014.
