9829 Murillo           Discovered 1973 Sept. 19 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Bartolomé Estéban Murillo (1618-1682) created many religious paintings for churches. The painter from Seville is famous for his genre pictures of children that were poor but happy, and these are imitated even today.
