Hermann Cäsar Hannibal Schubert (22 May 1848 in Potsdam, Germany – 20 July 1911 in Hamburg, Germany)[1] was a German mathematician. Schubert was one of the leading developers of enumerative geometry, which considers those parts of algebraic geometry that involve a finite number of solutions. In 1874, Schubert won a prize for solving a question posed by Zeuthen. Schubert calculus was named after him. Schubert tutored Adolf Hurwitz at the Realgymnasium Andreanum in Hildesheim, Hanover, and arranged for Hurwitz to study under Felix Klein at University.
