11585 Orlandelassus           Discovered 1994 Sept. 3 by E. W. Elst at the European Southern Observatory.
Orlande de Lassus (Roland Delattre, 1532-1594), a Franco-Flemish composer, is considered one of the most prolific and versatile composers of the late Renaissance. His 2000 works include motets, madrigals, chansons and lieder. Many of his masses are based on secular and even obscene themes.
