Paul Georg Funk (14 April 1886, Vienna – 3 June 1969, Vienna) was an Austrian mathematician who introduced the Funk transform and who worked on the calculus of variations.
Born in Vienna in 1886, he studied mathematics in Tübingen, Vienna, and Göttingen, writing his dissertation under the supervision of David Hilbert. He spent the interwar years in Prague as Professor of Mathematics at the Deutsche Technische Hochschule. Suspended from his professorship in 1939 on account of his being Jewish, Funk was deported to the Theresienstadt concentration camp in 1944, where he spent the last months of the war.
