Erika Pannwitz (May 26, 1904 in Hohenlychen — November 25, 1975 in Berlin[1]) was a German mathematician who worked in the area of geometric topology.
Life and work
Erika Pannwitz attended the Pannwitz-Freiluft school until 10th grade, and graduated from Augusta State School in Berlin in 1922. She studied mathematics in Berlin, and also for a semester in Freiburg (1925) and Göttingen (1928). After passing her teaching exam in 1927 (in mathematics, physics, and chemistry), she obtained her PhD in 1931 from Heinz Hopf at Freidrich-Wilhelms University. Her PhD thesis, which appeared two years later in Mathematischen Annalen, was honored summa cum laude. In her thesis, she established that every piecewise linear knot in general position has a quadrisecant, i.e., four collinear points. The topic was suggested to her by Otto Toeplitz.
In September 1930, Pannwitz became an editor of Jahrbuch über die Fortschritte der Mathematik. From 1940 to 1945, she work the cryptography service (with Helmut Grunsky) and then for a year as a scientific assistant at Marburg University. In 1946, she returned to Berlin to work as an editor for Zentralblatt für Mathematik. After mandatory retirement (in East Germany) in 1964, she worked at the Zentralblatt office in West Berlin until 1969.
