Georg Bohlmann

Georg Bohlmann ( born April 23, 1869 in Berlin, † April 25, 1928 ) was a German mathematician, focusing on the theory of probability and actuarial science.

Life

Georg Bohlmann went to school in Berlin and Leipzig in 1888 and made his Abitur at the Wilhelms -Gymnasium in Berlin. Then he began to study mathematics in Berlin Kronecker, Fuchs and Dilthey. More and more it advanced the Lie groups into the center of his interest. Since this area was poorly represented in Berlin, he moved to the University of Halle, where he 1892 Albert Wangerin with the topic About doctorate in a certain class continuirlicher groups and their relation with the addition theorems. After that, he worked at the Meteorological Institute in Berlin, where presumably his interest was aroused for Applied Mathematics. At the invitation of Felix Klein, he moved to Göttingen, where he habilitated in 1894. In 1895 he was involved in the founding of the Göttingen seminar for insurance science. However, since he had no permanent position there, he went in 1903 as Chief Actuary for the German subsidiary of the New York Mutual Life Insurance to Berlin.

In 1901 he wrote the article about life insurance mathematics the Encyclopedia of Mathematical Sciences, where he gave the probability theory long before Andrei Kolmogorov (1933), an axiomatic basis, in particular, he was also the first modern definition of stochastic independence. In comparison to the current structure of the probability theory only lacked the technical condition of the sigma- additivity. In contrast to Kolmogorov there Bohlmann however, were unable to demonstrate significant rates under its axiomatics. This gave little attention to his fundamental work on the theory of probability. In particular, Kolmogorov had, though he stayed several times in the late 1920s in Göttingen, no knowledge of Bohlmann work.
