Oskar Becker

Oskar Joachim Becker ( born September 5, 1889 in Leipzig, † November 13, 1964 in Bonn ) was a German philosopher, logician and mathematician. It belongs next to Martin Heidegger to the main pupils of Edmund Husserl. He was the academic teachers such as Max Bense, Paul Lorenzen, Hans Sluga, Jürgen Habermas, Karl- Otto Apel, Karl -Heinz Ilting, Hermann Schmitz, Elizabeth Ströker and Otto Pöggeler.

Life and work

Becker was a pupil of the St. Thomas School in Leipzig. After studying physics, chemistry, psychology, mathematics and philosophy at New College, Oxford and at the University of Leipzig Becker received his doctorate in 1914 in Leipzig by Otto Hölder with a thesis about the decomposition of a polygon into exclusive triangles on the basis of the plane axioms of logic and arrangement. From 1915 to 1918 he made ​​war service on the Eastern and Western fronts of World War II. From 1919, he studied under Edmund Husserl and Martin Heidegger in Freiburg. There he completed his habilitation in 1922, with the work contributions to the phenomenological justification of geometry and its physical applications. Then Becker was with Heidegger Husserl assistant. Becker was, inter alia, friends with Karl Ludwig Ferdinand Clauss Lowith and with. In 1927 he became an adjunct professor in Freiburg. In 1931 he was appointed professor at the University of Bonn, where he taught until his retirement in 1955, from 1946 to 1951 he was, although not a member of the NSDAP, been placed into temporary retirement due to his attitude and role in the era of National Socialism.

Oskar Becker has made major contributions to mathematical research, in which he represents a constructivist, intuitionism positions that are close, the history of mathematics (especially to Greek mathematics, Eudoxus example ) and submitted for modal logic. In addition, he has been busy in dealing with the philosophy of Martin Heidegger, with problems of existential philosophy and aesthetics. In Bonn he had with Otto Toeplitz before the war a historical mathematics seminar.
