André Weil (May 6, 1906 - August 6, 1998) was a prominent French mathematician famous in particular for his work with number theory and algebraic geometry. He was also one of the founders of the Bourbaki Group. Among his major accomplishments are the 1940s proof of the Riemann hypothesis for zeta-functions of curves over finite fields and his subsequent laying of proper foundations for algebraic geometry to support that result. Other significant results were on Pontryagin duality and differential geometry. Weil wrote several books and papers on mathematics. He is mentioned as possibly autistic (Asperger's Syndrome) in Autism and Mathematical Talent by Ioan James. His sister Simone Weil is also believed to have been autistic.
