Alwin Korselt was born there in 1864.
After attending Gymnasium in Zittau between 1876 and 1885, he studied mathematics and physics in Leipzig (with one semester in 1886 in Freiburg im Breisgau) until 1890.
He discovered Korselt"s Criterion which provides a definition for Carmichael numbers and also contributed an early result in relational algebra. Korselt"s 1902 dissertation at Leipzig University (adviser Otto Hölder) was titled Über die Möglichkeit der Lösung merkwürdiger Dreiecksaufgaben durch Winkelteilung ("On the Possibility of Solving Strange Triangle Problems by Angle Dissection"). Shortly afterwards he took part in controversy with Gottlob Frege, concerning Hilbert"s axioms for the foundations of Euclidean geometry.
He was treated by Frege as a partisan of Hilbert.
Korselt was influenced by Bolzano and had contact with Pringsheim, Hilbert, Russell, Fraenkel and Carathéodory.
