Georg Bohlmann (23 April 1869 – 25 April 1928) was a
actuarial mathematics
.
Life and career
Georg Bohlmann went to school in
Albert Wangerin with a dissertation on the topic Ueber eine gewisse Klasse continuierlicher Gruppen und ihren Zusammenhang mit den Additionstheoremen ("On a certain class of continuous groups and their relation to addition theorems").[1] After that, he worked at the Meteorological Institute of Berlin, where presumably his interest in applied mathematics developed. At the invitation of Felix Klein, he moved to the University of Göttingen, where he habilitated
in 1894. In 1895, he was involved in starting a seminar on actuarial science at Göttingen. However, since he held no permanent position there, he went to Berlin in 1903 to work as the Chief Actuary for the German subsidiary of the New York Mutual Life Insurance Company.
In 1901, he wrote the entry on life insurance mathematics in the sigma additivity. However, in contrast to Kolmogorov, Bohlmann failed to prove significant theorems within his axiomatic framework. As a result, his fundamental contributions to probability theory gained very little attention. In particular, though Kolmogorov had visited Göttingen several times in the late 1920s, he had no knowledge of Bohlmann's work.
Bohlmann was an invited speaker in the International Congress of Mathematicians in 1908 at Rome.[2][3]
