Maximilian Krafft, 1930 in Jena

Maximilian Krafft (born November 3, 1889 in Pyrbaum , Upper Palatinate , † June 26, 1972 in Marburg ) was a German mathematician .

Life

As the son of the general practitioner R. Krafft, he graduated from high school in Offenbach am Main . From 1908 to 1913 he studied at the Universities of Heidelberg , Munich and Marburg , where in 1913 he obtained the scientific teaching state exam and in 1914 with the excited by Ludwig Neumann dissertation On the theory of Faber's polynomials and their associated functions to Dr. phil. received his doctorate .

From 1914 to 1916 he was an assistant at the University of Göttingen . From June 1916 to November 1918 he did military service. From 1920 to 1922 he was a study assessor. From 1922 to 1926 he was assistant to Robert König (1885–1979) at the University of Münster and after his habilitation in 1923 he was a private lecturer . In 1926 he completed his habilitation at the University of Marburg , where he became an adjunct professor in 1927 and an adjunct professor in 1940. In November 1933 he signed the German professors' confession of Adolf Hitler . In 1956 he retired. From 1962 to 1967 he was a lecturer in the history of mathematics at the University of Frankfurt am Main .

With König he wrote the textbook Elliptic Functions (W. de Gruyter, Berlin 1928), in which they introduce elliptic functions as a meromorphic function on a two-leaf Riemann surface . They also go into the algebraic development of the theory from the function body standpoint (called arithmetic at the time , since the corresponding developments by Richard Dedekind , Leopold Kronecker and Kurt Hensel and Georg Landsberg were partly motivated by number theory).
