Ernesto Teodoro Moneta (1833–1918) was an Italian journalist, revolutionary soldier and later a pacifist. He won the 1907 Nobel Peace Prize “for his work in the press and in peace meetings, both public and private, for an understanding between France and Italy.” His motto ‘In varietate unitas!’ later inspired the motto of the European Union.Naming citation (WGSBN Bull. 2, #7, 7), IAU / Minor Planet Center, via NASA/JPL
