Janina Hosiasson-Lindenbaum

Janina Hosiasson-Lindenbaum (December 5, 1899—April 1942) was a Polish logician and philosopher. She published some twenty research papers along with translations into Polish of three books by Bertrand Russell. The main focus of her writings was on foundational problems related to probability, induction and confirmation. She is noted especially for authoring the first printed discussion of the Raven Paradox which she credits to Carl Hempel and the probabilistic solution she outlined to it. Shot by the Gestapo in 1942, she, like her husband Adolf Lindenbaum, and many other eminent representatives of Polish logic, shared the fate of millions of Jews murdered on Polish soil by the Nazis.
