3821 Sonet           Discovered 1985 Sept. 6 by H. Debehogne at the European Southern Observatory.
Jean Sonet (1908-1987), a Belgian Jesuit, was a specialist in Romance languages, professor and later rector (1953-1958) of the University of Namur. From 1958 to his death he was Vice-Rector of the Catholic University of Cordoba (Argentina), where the discoverer met him. The name was suggested by A. Sonet.
