Felix Kaufmann (4 July 1895, Vienna – 23 December 1949, New York) was an Austrian-American philosopher of law.
In 1938, the conditions for Jewish scholars became too hard and he left for the USA.
There he taught until his death as a law professor, in the Graduate Faculty of the New York School for Social Research.
Kaufmann also aided fellow Austrian emigres in need of assistance during the pre-war years when the situation became dire for Jewish academics and scholars in Germany and Austria.
After moving to the United States he was invited to write a similar book in English, but what he produced (Kaufmann 1944) was significantly different, under the influence of Dewey's Logic: The Theory of Inquiry.
