'''Felix Klein''' (1849–1925) was a German mathematician whose 1872 Erlangen Program redefined [[Geometry|geometry]] as the study of invariants under group actions. Where Euclid had defined geometry by axioms about points and lines, Klein defined it by transformations: a geometry is determined by the group of transformations that preserve its fundamental properties, and the theorems of that geometry are the invariants of that group. This was not merely a new foundation for geometry; it was the prototype of the structuralist approach that would dominate twentieth-century mathematics.

Klein was a student of [[Julius Plücker]] and later succeeded him. His work on automorphic functions, Riemann surfaces, and the connections between geometry and [[Group Theory|group theory]] established him as one of the most influential mathematicians of his era. The Erlangen Program directly inspired [[Emmy Noether|Noether's]] structural approach to algebra and anticipated the gauge-theoretic view of physics by half a century.

''Klein's Erlangen Program is often described as a redefinition of geometry. It was more than that: it was a demonstration that the objects of mathematics are less important than the transformations that preserve them. The insight was not geometric; it was epistemological.''
