Oskar Bolza (born May 12, 1857 in Bergzabern , Bavarian Palatinate , † July 5, 1942 in Freiburg im Breisgau ) was a German mathematician .

Life

Bolza 's father, Moritz Emil Bolza (1828–1891), was a judge, the father of his mother Luise Koenig (1830–1928), Friedrich Koenig , inventor of the high-speed press. Oskar Bolza 's brother Albrecht Bolza (May 19, 1862 in Dahn , † July 25, 1943) took over the grandfather's printing press company. Oskar Bolza's sister, Eleonore Bolza , lived from October 14, 1864 (Dahn) to February 3, 1923 (Hildesheim).

Oskar Bolza first studied mechanical engineering, then physics and from 1878 mathematics in Berlin (with Karl Weierstrass ), Heidelberg , Strasbourg and Göttingen (with Hermann Amandus Schwarz ). After passing the state examination, he first taught at a grammar school in Freiburg, but then did his doctorate in Göttingen in 1886 with Felix Klein . In 1887 he was in England (Cambridge, Edinburgh, London) and then went to the USA. In 1888 he was a reader at Johns Hopkins University in Baltimore , in 1889 an associate professor at Clark University in Worcester and from 1893 at the newly founded University of Chicago (at the same time an international mathematicians' congress was held there for the world exhibition, with Felix Klein taking part), where he became a professor in 1894. In 1910 he went back to Germany, where he was honorary professor at the University of Freiburg and was retired in 1933. At the same time he remained an honorary professor in Chicago.

He was a member of the American Mathematical Society and the German Mathematicians Association .

Bolza became known for his derivation of the reduction from hyperelliptic to elliptic integrals and his contributions in the field of the calculus of variations , which he further developed following his teacher Weierstrass as well as Adolf Kneser and David Hilbert . In 1901 his textbook Lectures on the calculus of Variations was published . The German edition came out for the first time in 1909 and then again as an unchanged reprint in 1949.

Later he dealt with religious topics and languages, for which he studied Sanskrit . In 1930 he published the book Faithless Religion under the pseudonym F. H. Marneck . In 1912 Bolza was appointed a member of the Leopoldina .

Gilbert Ames Bliss is one of his students .

Hans Bolza was his nephew.
