Jean Alexandre Eugène Dieudonné (born July 1, 1906 – died November 29, 1992) was a famous French mathematician. He was known for his important work in different areas of mathematics. These included abstract algebra, algebraic geometry, and functional analysis.

Dieudonné was also a key member of a special group of mathematicians called Nicolas Bourbaki. This group wrote many influential math books together. He also worked closely with another great mathematician, Alexander Grothendieck. Together, they worked on a big project called Éléments de géométrie algébrique. Jean Dieudonné also wrote about the history of mathematics.

Early Life and Learning

Jean Dieudonné was born and grew up in Lille, France. He spent some time in England when he was young. This is where he first learned about algebra, a type of mathematics.

In 1924, he was accepted into a very good school called the École Normale Supérieure. Here, he studied complex analysis, which is a branch of mathematics. One of his classmates was another famous mathematician, André Weil. In 1934, Jean Dieudonné joined a group of mathematicians. This group later became known as 'Bourbaki'.

Teaching and Career

Jean Dieudonné served in the French Army during World War II. After the war, he taught in Clermont-Ferrand, France. He then became a professor at several universities around the world.

He taught at the University of São Paulo in Brazil from 1946 to 1947. Then he taught at the University of Nancy in France from 1948 to 1952. He also taught in the United States at the University of Michigan (1952–1953) and Northwestern University (starting in 1953).

Later, he returned to France. He helped start the Institut des Hautes Études Scientifiques, a famous research institute. In 1964, he moved to the University of Nice. There, he helped create the Department of Mathematics. He retired from teaching in 1970. In 1968, he was chosen to be a member of the Académie des Sciences. This is a great honor for scientists in France.

Important Works

Jean Dieudonné wrote many important math books. He helped write many volumes for the Bourbaki series. He also wrote many books for the EGA series. This series was about algebraic geometry.

He also wrote nine volumes of his own series called Éléments d'analyse. The first book in this series was also published in English as Foundations of Modern Analysis. It became a very popular textbook for university students studying functional analysis.

Dieudonné also wrote other books on different math topics. These included Infinitesimal Calculus and Linear Algebra and Elementary Geometry. He also wrote about invariant theory, commutative algebra, and formal groups.

He helped guide the early research of Alexander Grothendieck. From 1959 to 1964, Dieudonné worked with Grothendieck at the Institut des Hautes Études Scientifiques. They worked together to explain new ideas in algebraic geometry.
