Hahn (-Neurath), Olga

*July 20, 1882 (Vienna, Austria)
† July 20, 1937 (The Hague, Netherlands)

Olga Hahn studied mathematics and philosophy at the University of Vienna from the winter semester 1902/03 until the summer semester 1909 (with interruptions). She was one of the most prominent female members of the Vienna Circle and the sister of the mathematician Hans Hahn. Although she became blind in 1904, when she was 22, she was able to finish her doctoral studies. In 1911, she became the third ever female graduate in philosophy at Vienna University. Her doctoral thesis Über die Koeffizienten einer logischen Gleichung und ihre Beziehungen zur Lehre von den Schlüssen (1911) received great compliments from her instructor, Adolf Stöhr, the successor to the chair of Ludwig Boltzmann. In 1912, Olga Hahn married Otto Neurath and became a regular participant in the Vienna Circle discussions. Due to the events of the Austrian Civil War (February 1934), Olga emigrated to the Netherlands, where she joined her husband. She died on her birthday three years later in The Hague from complications after an operation.

In 1909 Otto Neurath and Olga Hahn published a joint paper, in which the authors discussed Ernst Schröder’s algebra of logic. In the same time period, between 1909 and 1911, Otto Neurath and Olga Hahn published other articles on the same topic separately: three by Neurath, two by Olga. They all addressed primarily Schröder’s algebraic logic, who played a key role for the institutionalization of mathematical logic in Germany.
