Philipp Frank was an Austrian-American physicist, mathematician and philosopher of the early to mid 20th century, born in 1884. He studied physics at the University of Vienna and graduated in 1907 with a thesis in theoretical physics under the supervision of Ludwig Boltzmann, joining the faculty there in 1910. Albert Einstein recommended him as his successor for a professorship at the German Charles-Ferdinand University of Prague, which he held from 1912 until 1938. He was a logical positivist and a member of the Vienna Circle, influenced by Mach, and after the German invasion of Czechoslovakia he lectured on physics and mathematics at Harvard from 1938 until his retirement in 1954, founding the Institute for the Unity of Science in 1947.
