Gustav Bergmann (May 4, 1906 – April 21, 1987) was an Austrian-born American philosopher. He studied at the University of Vienna and was a member of the Vienna Circle. In the United States, he was a professor of philosophy and psychology at the University of Iowa.
Bergmann was born in Vienna, Austria-Hungary. He earned his Ph.D. in mathematics at the University of Vienna in 1928. His dissertation, directed by Walther Mayer, was titled Zwei Beiträge zur mehrdimensionalen Differentialgeometrie. While studying for his doctorate, he was invited to join the Vienna Circle, a group of philosophers, mathematicians, scientists, and others committed to a scientific worldview under the name of logical positivism. In 1930–31, he worked with Albert Einstein in Berlin. Unable as a Jew to find academic employment, Bergmann obtained a J.D. degree from the University of Vienna in 1935, and practiced corporate law until he and his family fled to the United States in 1938. Settling at the University of Iowa in Iowa City in 1939, Bergmann eventually became professor of both philosophy and psychology.
He died in Iowa City.
