Philipp Frank

Philipp Frank was an Austrian-American physicist, mathematician, and philosopher, known for his contributions to logical positivism and his membership in the Vienna Circle. Born in Vienna, Austria-Hungary, he studied physics at the University of Vienna under Ludwig Boltzmann. He began his academic career at the University of Vienna in 1910 and later held a professorship at the German Charles-Ferdinand University of Prague from 1912 to 1938. Albert Einstein recommended him for this position. During his time in Prague, he mentored doctoral students such as Reinhold Furth and Peter Bergmann. In 1938, following the German invasion of Czechoslovakia, Frank, who was Jewish, emigrated to the United States. He was invited by Harvard University to lecture on quantum theory and the philosophy of modern physics. He continued to lecture at Harvard on physics and mathematics until his retirement in 1954. In 1947, he established the Institute for the Unity of Science, associated with the American Academy of Arts and Sciences, which aimed to address the fragmentation of knowledge. Frank was politically a socialist. He died in Cambridge, Massachusetts, in 1966.
