+||Robert Wertheimer Frucht (later known as Roberto Frucht) (d. 26 June 1997) was a German-Chilean mathematician; his research specialty was graph theory and the symmetries of graphs. He is known for Frucht's theorem, the result that every group can be realized as the group of symmetries of an undirected graph, and for the Frucht graph, one of the two smallest cubic graphs without any nontrivial symmetries. Pic = Frucht's graph.
