Leopold Gegenbauer

Leopold Bernhard Gegenbauer (2 February 1849, Asperhofen – 3 June 1903, Gießhübl) was an Austrian mathematician remembered best as an algebraist.

After graduating from Berlin, Gegenbauer was appointed to the position of extraordinary professor at the University of Czernowitz (modern Chernivtsi, Ukraine) in 1875, at that time in the Austrian Empire.

He remained in Czernowitz for three years before moving to the University of Innsbruck where he worked with Otto Stolz.

Among the students who studied with him at Vienna were the Slovenian Josip Plemelj, the American James Pierpont, Ernst Fischer, and Lothar von Rechtenstamm.

Gegenbauer also gave his name to arithmetic functions studied in analytic number theory.
