Hans Reichenbach

Hans Reichenbach was a leading philosopher of science, an educator, and a proponent of logical empiricism. He founded the Gesellschaft fur empirische Philosophie, the Society for Empirical Philosophy, in Berlin in 1928, an organization also known as the Berlin Circle, whose members came to include Carl Gustav Hempel, Richard von Mises, David Hilbert, and Kurt Grelling. In 1930 Reichenbach and Rudolf Carnap became editors of the journal Erkenntnis. He made lasting contributions to the study of empiricism grounded in a theory of probability, to the logic and philosophy of mathematics, to the study of space, time and relativity theory, to the analysis of probabilistic reasoning, and to the philosophy of quantum mechanics. In 1951 he published The Rise of Scientific Philosophy, his most widely read book.
