Felix Klein
1849–1925
A brilliant architect of modern geometry, this German mathematician helped show how symmetry could unify seemingly different kinds of space. He was also a major force in mathematics education, shaping how the subject was taught well beyond the university world.

About the author
Born in Düsseldorf in 1849, Felix Klein became one of the most influential mathematicians of his time. He is especially remembered for the Erlangen Program of 1872, which reframed geometry by focusing on the properties that stay unchanged under groups of transformations. That idea helped connect geometry, algebra, and later developments across modern mathematics.
Klein worked in several major centers of learning, including Erlangen, Munich, Leipzig, and Göttingen. Alongside important research in group theory, complex analysis, and non-Euclidean geometry, he had a gift for bringing different mathematical ideas together and showing their deeper unity.
He also cared deeply about teaching. In Göttingen, he helped build mathematics into a strong research community and pushed for reforms in mathematical education, especially in the training of teachers and in linking school mathematics with university work. He died in Göttingen in 1925, leaving a legacy that shaped both advanced mathematics and the way it is taught.
