Hans Grauert (8 February 1930 in Haren, Emsland, Germany - 4 September 2011) was a German mathematician. He is known for major works on several complex variables, complex manifolds[1] and the application of sheaf theory in this area, which influenced later work in algebraic geometry.[2] Together with Reinhold Remmert he established and developed the theory of complex-analytic spaces.[3] He became professor at the University of Göttingen in 1958, as successor to C. L. Siegel. The lineage of this chair traces back through an eminent line of mathematicians: Weyl, Hilbert, Riemann, and ultimately to Gauss.[4] Until his death, he was professor emeritus at Göttingen.
Grauert was awarded a fellowship of the Leopoldina.[5]
Grauert attended school at the Gymnasium in Meppen before studying for a semester at the University of Mainz in 1949, and then at the University of Münster, where he was awarded his doctorate in 1954.[5]
