Georg Alexander Pick

Georg Alexander Pick (10 August 1859 to 26 July 1942) was an Austrian Jewish mathematician who was murdered during the Holocaust. Born in Vienna, he died at the Theresienstadt concentration camp. He is best known today for Pick's theorem for determining the area of lattice polygons, which he published in an article in 1899 and which was popularized when Hugo Dyonizy Steinhaus included it in the 1969 edition of Mathematical Snapshots. Pick studied at the University of Vienna, defended his Ph.D. in 1880 under Leo Königsberger and Emil Weyr, and was then an assistant to Ernst Mach at the Charles-Ferdinand University in Prague, where he remained until his retirement except for a year working with Felix Klein at Leipzig.
