57658 Nilrem (2001 UJ1) is a main-belt asteroid discovered on October 17, 2001 by M. Ory at Vicques.
It is named after Jean-Claude Merlin (b. 1954), a technician in process computing in Le Creusot, France, an observer of comets and asteroids for more than 30 years. He wrote many papers for astronomical magazines and several books about minor planets. He is the founder-president of the Société Astronomique de Bourgogne. Nilrem changes to "Merlin" spelled backwards.
