Hermann Schwarz (25 January 1843 – 30 November 1921) was a German
mathematician, known for his work in
complex analysis. Between 1867 and 1869, he worked at the
University of Halle, then at the
Swiss Federal Polytechnic in Zurich. From 1875, Schwarz worked at
Göttingen University, dealing with the subjects of complex analysis,
differential geometry, and the
calculus of variations. In 1892, he became a member of the Berlin Academy of Science and a professor at the
University of Berlin, where his students included
Lipót Fejér,
Paul Koebe and
Ernst Zermelo. Schwarz's name is attached to many ideas in mathematics. This photograph of Schwarz, taken around 1890, is in the collection of the
ETH Library.
