29197 Gleim           Discovered 1991 Jan. 15 by F. Borngen at Tautenburg.
Johann Wilhelm Ludwig Gleim (1719-1803) was secretary of the cathedral chapter at Halberstadt. He wrote odes in imitation of Horace and Anacreon, rhymed fables, romances and patriotic songs. His patronage of fledgling poets earned him the affectionate appellation of "Father Gleim".
