7387 Malbil           Discovered 1982 Jan. 30 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Named in honor of Malcolm Bilson (b. 1935), Frederick J. Whiton Professor of Music at Cornell University. Best known as a pianist, Bilson has recorded scintillating performances of music by Mozart, Beethoven and others. His research interests center on music of the late eigteenth and nineteenth centuries, performance practice, problems of notation and execution, instruments and musical aesthetics. He has won several awards. Bilson gave a recital at the "Asteroids, Comets, Meteors" meeting at Cornell University in July 1999.
