29298 Cruls           Discovered 1993 Sept. 16 by H. Debehogne and E. W. Elst at the European Southern Observatory.
Luis Cruls (1848-1908) was a Belgian-born Brazilian astronomer and geodesist. Director of the Brazilian National Observatory and co-discoverer of the Great Comet in 1882, he observed also the 1882 transit of Venus from Punta Arenas, Chile.
