Erika Pannwitz

from Wikipedia, the free encyclopedia

Erika Pannwitz (born May 26, 1904 in Hohenlychen , † November 25, 1975 in Berlin ) was a German mathematician who worked in the field of geometric topology . From 1953 to 1969 she headed the Zentralblatt der Mathematik , one of the world's two leading specialist journals on mathematics.

life and work

Example of a quadruple tendon of a knot (clover leaf loop)

Erika Pannwitz attended the Pannwitz Open Air School in Lychen up to the tenth grade and graduated from the Augusta School in Berlin in 1922. She studied mathematics in Berlin and one semester each in Freiburg (1925) and Göttingen (1928). After teaching exam in 1927 (mathematics, physics and chemistry), it was in 1931 Heinz Hopf (PhD supervisor), Erhard Schmidt and Issai Schur at the Friedrich-Wilhelms University doctorate . Her doctoral thesis , which only appeared in the Mathematische Annalen two years later , was awarded opus eximium (this is the top grade; the better known name for it is summa cum laude ). In her doctoral thesis, Pannwitz examined so - called quadruple tendons of knots and tangles . She received the suggestion for this investigation from Otto Toeplitz .

From September 1930 Erika Pannwitz worked on the yearbook on the progress of mathematics , the mathematical department . From 1940 to 1945 she was with the cipher service of the Foreign Office (like Helmut Grunsky ) and then for a year a research assistant at the University of Marburg . In 1946 she returned to Berlin to work at the German Academy of Sciences for the Zentralblatt der Mathematik . From 1947 she was permanently employed there, from 1953 head of the Zentralblatt department . After reaching retirement age (in the GDR) in 1964, she headed the Zentralblatt office in West Berlin until 1969.
