Guy Hirsch

Guy Hirsch (20 September 1915 – 4 August 1993) was a Belgian mathematician and philosopher of mathematics, who worked on algebraic topology and epistemology of mathematics.

He became a member of the Royal Flemish Academy of Belgium for Science and the Arts in 1973.

He is known for the Leray–Hirsch theorem, a basic result on the algebraic topology of fiber bundles that he proved independently of Jean Leray in the late 1940s.
