15355 Maupassant           Discovered 1995 Jan. 2 by E. W. Elst at Caussols.
Guy de Maupassant (1850-1893) was a French writer showing a remarkable hostility to religion. Impregnated with a natural aversion against society, he loved wandering through nature. A master of short-stories and novels, in which he describes accurately human vices, he became famous with the 1885 novel Bel Ami.
