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.

The lineage of this chair traces back through an eminent line of mathematicians: Weyl, Hilbert, Riemann, and ultimately to Gauss.

Grauert was awarded a fellowship of the Leopoldina[5] and the von Staudt Prize.
