I held a chair in mathematics at Erlangen when I was only 23 years old.
Some of my mathematics research was not universally accepted by my colleagues because the ideas were so revolutionary.
The journal, Mathematische Annalen, flourished under my management and specialized in complex analysis, algebraic geometry and invariant theory.
In 1875, I married the granddaughter of the famous philosopher Georg Wilhelm Friedrich Hegel.
I am best known for my work in the areas of topology and non-Euclidean geometry, and even have a special bottle named after me (that if you cut it in half, it would form two moebius strips).
Felix Christian Klein (1849-1925)
