Georg Bohlmann
Georg Bohlmann (born April 23, 1869 in Berlin ; † April 25, 1928 there ) was a German mathematician specializing in probability theory and actuarial mathematics .
Life
Georg Bohlmann went to school in Berlin and Leipzig and graduated from Wilhelms-Gymnasium in Berlin in 1888 . Then he began to study mathematics under Kronecker , Fuchs and Dilthey in Berlin. The Lieschen groups increasingly became the focus of his interest. Since this area was poorly represented in Berlin, he moved to the University of Halle , where he did his doctorate in 1892 under Albert Wangerin on the subject of a certain class of continuous groups and their connection with the addition theorems . He then worked at the Meteorological Institute in Berlin, where his interest in applied mathematics was probably aroused. At the invitation of Felix Klein , he moved to Göttingen, where he completed his habilitation in 1894. In 1895 he was involved in founding the Göttingen Institute for Insurance Science. Since he could not find a permanent position there, however, he went in 1903 as chief mathematician to the German subsidiary of New York Mutual Life Insurance in Berlin.
In 1901 he wrote the article on life insurance mathematics in the Encyclopedia of Mathematical Sciences , where he gave the theory of probability an axiomatic basis long before Andrei Kolmogorow (1933), in particular he was the first to give the modern definition of stochastic independence . Compared to the current structure of probability theory, only the technical condition of sigma additivity was missing . In contrast to Kolmogorow, however, Bohlmann did not succeed in proving significant theorems within the framework of his axiomatics. As a result, his fundamental work on probability theory received little attention. In particular, Kolmogorow, although he stayed in Göttingen several times in the late 1920s, had no knowledge of Bohlmann's work.
