13118 La Harpe           Discovered 1993 Oct. 20 by E. W. Elst at the European Southern Observatory.
Jean François de la Harpe (1739-1803) was a French writer and a bitter and caustic man. Although unsuccessful in his other writings, he will be always remembered for his Abrégé de l´Histoire générale des Voyages (1780), a 32-volume set that gives a complete review of famous voyages during historical times.
