Henri Cartan

About

Henri Cartan was one of the most influential French mathematicians of the twentieth century, renowned for his foundational contributions to algebraic topology, complex analysis, homological algebra, and sheaf theory. Born in Nancy, France, as the son of the eminent mathematician Elie Cartan, he studied at the Ecole Normale Superieure in Paris, where he later became a highly influential professor. Through his famous Seminar Cartan, which ran from 1948 to 1964, he shaped generations of French and international mathematicians. Cartan is widely recognized as a founding member of the Nicolas Bourbaki group, a collective of French mathematicians who sought to reformulate mathematics on a highly rigorous and axiomatic basis. His collaboration with Samuel Eilenberg led to the publication of Homological Algebra in 1956, a seminal text that defined the entire field. Throughout his life, Cartan was also a dedicated defender of human rights, actively advocating for dissident scientists behind the Iron Curtain. He served as the president of the International Mathematical Union from 1967 to 1970 and received numerous accolades, including the CNRS Gold Medal in 1976 and the Wolf Prize in Mathematics in 1980.
