3820 Sauval           Discovered 1984 Feb. 25 by H. Debehogne at the European Southern Observatory.
Henri Sauval (1623-1676) was a French legal expert at the High judicial Court of Paris in the age of the Sun King, Louis XIV, and also a scrupulous historian and author of Histoire et recherches des antiquités de la ville de Paris (1724). The name was suggested by A. J. Sauval.
