Felix Klein

Christian Felix Klein was a German mathematician and mathematics educator, known for his work in group theory, complex analysis, nonEuclidean geometry, and on the connections between geometry and group theory. His 1872 Erlangen Program, classifying geometries by their underlying symmetry groups, was a hugely influential synthesis of much of the mathematics of the day.

Felix Klein was born onApril 1849 in Dsseldorf, to Prussian parents his father, Caspar Klein , was a Prussian government officials secretary stationed in the Rhine Province. Kleins mother was Sophie Elise Klein . He attended the Gymnasium in Dsseldorf, then studied mathematics and physics at the University of Bonn, 18651866, intending to become a physicist. At that time, Julius Plcker held Bonns chair of mathematics and experimental physics, but by the time Klein became his assistant, in 1866, Plckers interest was geometry. Klein received his doctorate, supervised by Plcker, from the University of Bonn in 1868.
