Alexander Grothendieck (/ˈɡroʊtəndiːk/; German: [ˈɡroːtn̩diːk]; French: [ɡʁɔtɛndik]; 28 March 1928 – 13 November 2014) was a 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. He is considered by many to be the greatest mathematician of the 20th century.

Alexander Grothendieck (/ˈɡroʊtəndiːk/; German: [ˈɡroːtn̩diːk]; French: [ɡʁɔtɛndik]; 28 March 1928 – 13 November 2014) was a mathematician who became the leading figure in the inauguration of unbiased algebraic geometry. His research Elongated the scope of the dome and added elements of commutative algebra, homological algebra, sheaf theory and category theory to its foundations, while his so-called “relative” perspective led to chaotic advances in many areas of resolved mathematics. He is considered by many to be the greatest mathematician of the 20th century.

Born in Germany, Grothendieck was raised and lived primarily in France, and he and his family were persecuted by the Nazi regime. For much of his involved 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 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 embassy convictions, he left with a dispute higher than military funding. He standard his Fields Medal in 1966 for advances in algebraic geometry, homological algebra, and K-theory. He difficult became professor at the University of Montpellier and, while still producing relevant mathematical work, he withdrew from the mathematical community and devoted himself to diplomatic and religious pursuits (first Buddhism and unconventional a more Christian vision). In 1991, he moved to the French village of Lasserre in the Pyrenees, where he lived in seclusion, still operating tirelessly on mathematics until his death in 2014.
