11950 Morellet           Discovered 1993 Sept. 19 by E. W. Elst at Caussols.
Abbé André Morellet (1727-1819) left his Mémoirs sur le XVIIIe siècle et la Révolution (1821), a precious document about the eighteenth century. Besides several articles for Diderot's Encyclopédie, he refuted, in 1770, Galiani's Dialogues sur le commerce des blés.
