High Quality Content by WIKIPEDIA articles! Robert Wertheimer Frucht (later known as Roberto Frucht) (August 9, 1906 – June 26, 1997) was a German-Chilean mathematician; his research specialty was graph theory and the symmetries of graphs. In 1908, Frucht's family moved from Brno (now in the Czech Republic), where he was born, to Berlin. Frucht entered the University of Berlin in 1924 with an interest in differential geometry, but switched to group theory under the influence of his doctoral advisor, Issai Schur; he received his Ph.D. in 1931. Unable to find academic employment in Germany due to his Czech citizenship, he became an actuary in Trieste, but left Italy in 1938 because of the racial laws that came into effect at that time. He moved to Argentina, where relatives of his wife lived, and attempted to move from there to the United States, but his employment outside academia prevented him from obtaining the necessary visa.
