Ernst Zermelo
contemporaryMathematical Logic, Foundations of Mathematics1871 – 1953
Ernst Zermelo (1871–1953) was a German mathematician and logician whose work on the foundations of mathematics was foundational to modern set theory. He is best known for formulating the first rigorous axiomatization of set theory and for proving the well-ordering theorem. His philosophical work touched on questions of mathematical truth, conventionalism, and the nature of geometric and logical axioms.
