Jean Giraud (French: [ʒiʁo]; 2 February 1936 – 27 or 28 March 2007)[1][2] was a French mathematician, a student of Alexander Grothendieck.[3] His research focused on non-abelian cohomology and the theory of topoi. In particular, he authored the book Cohomologie non-abélienne (Springer, 1971) and proved the theorem that bears his name, which gives a characterization of a Grothendieck topos.[4]

From 1969 to 1989, he was a professor at École normale supérieure de Saint-Cloud.[1]

From 1993 to 1994, he was deputy director for research of École normale supérieure de Lyon, where he was made interim director in 1994 and director from 1995 to 2000.[2]
