Hilda Geiringer

Hilda Geiringer von Mises previously Hilda Hilda Pollaczek also Polatschek ( published as Hilda Geiringer Hilda Pollaczek - Geiringer or ); married von Mises; Born September 28, 1893 in Vienna; † March 22, 1973 in Santa Barbara ( California)) was an Austrian- American mathematician who worked on elasticity theory and statistics. She was the first lecturer in Germany for Applied Mathematics. She was Jewish.

Family

Geiringer comes from the family of the Hungarian textile manufacturer Ludwig Geiringer and his wife Martha nee Wertheimer. Her siblings were later obtained his doctorate Ernst Geiringer, who later became engineer Peter Geiringer and the later musicologist Karl Geiringer ( 1899-1989 ).

Life

Before the First World War she was active in the youth movement, for example in the educational experiment of the " kindergarten Baumgarten ". She studied mathematics at the University of Vienna, where she graduated in 1917 with Wilhelm Wirtinger via Fourier series in two variables. She then worked 1918/19, in the editorial of the " Yearbook of the progress of mathematics " under Leon Lichtenstein, returned in 1919 shortly after Vienna back to work as a teacher and community college teacher and went in 1921 as an assistant at the Institute for Applied Mathematics to Richard von Mises to Berlin. There, she married Felix Pollaczek statisticians, like she came from Vienna and received his PhD in Berlin in Isay Schur. In 1922 the marriage was dissolved, and Hilda Geiringer moved their daughter on alone. As assistant to von Mises, she worked in the field of statistics and the theory of plasticity. In 1927 she qualified as a professor in Berlin and was a lecturer. With the power of the National Socialists in 1933 ended their hopes of a already asked the prospect associate professor. As a Jew, she was dismissed from the University and followed ( after a short time at the Institute of Mechanics in Brussels) finally Richard von Mises in 1934 to Istanbul, where it built a new Mathematics Institute, where she was a professor (in the beginning, she taught in French, later in Turkish). 1939 both moved on to the U.S., since they were the political situation in Turkey too uncertain. Hilda Geiringer taught first at Bryn Mawr College. 1942, while she carried out secret work for the U.S. government, held at Brown University lectures on geometry of mechanics, whose transcripts were widely spread. In 1943, she married von Mises and became a professor at Wheaton College in Norton (Massachusetts ) to be closer to Mises at Harvard University. 1953 she was after the death of Mises whose collected works out ( as a Research Fellow at Harvard ) and his posthumous " Mathematical theory of probability and statistics " (1964) and his " Mathematical theory of compressible fluid flow" (1958). In 1959 she retired from teaching at Wheaton College, after she was promoted in 1956 at the Free University of Berlin, associate professor emeritus at full retirement salary.

In 1930 she developed the " Geiringer equations " for plane plastic deformation. Appeared in 1958 in the "Handbook of Physics" (Ed. Siegfried Flügge ) their review article on plasticity theory with Alfred M. Freudenthal ( " The mathematical theory of the inelastic continuum ").

Geiringer was a member of the American Academy of Arts and Sciences. In 1960 she received an honorary doctorate from Wheaton College. 1967 organized by the University of Vienna for their 50 -year-old doctor anniversary ( Golden Promotion) a celebration.
