Wilhelm Johann Eugen BlaschkeDied 17 Mar 1962 at age 76 (born 13 Sep 1885).German mathematician whose major contributions to geometry concerned kinematics and differential geometry. Kinetic mapping (important later in the axiomatic foundations of various geometries) he both discovered and established it as a tool in kinematics. He also initiated topological differential geometry (the study of invariant differentiable mappings). |
