Women of the Vienna Circle

Among the members of the Vienna Circle were a female philosopher, Rose Rand, and two female mathematicians, Olga Hahn-Neurath and Olga Taussky. Olga Hahn (1882-1937) was the sister of Hans Hahn, the mathematician, and fellow member of the Vienna Circle. She studied mathematics and philosophy at the University of Vienna from 1902, and received her PhD in 1911. Hahn was triply marginalized as a woman, a Jewish scholar, and a person with a disability. She had become blind at the age of 22 as the result of an inflammation of the optic nerve. While still writing her PhD, she published her first paper on the algebra of classes in Schröder's logic, setting out to axiomatize Schröder's system (Hahn 1909). Soon afterwards, she and Neurath published a joint paper, proposing key revisions to the axioms and proof procedure of Schröder's system (Hahn and Neurath 1909). Hahn was awarded her PhD for a paper on the theory of inference (Hahn 1910).
