15239 Stenhammar           Discovered 1989 Feb. 4 by E. W. Elst at the European Southern Observatory.
Carl Wilhelm Eugen Stenhammar (1871-1927) was a Swedish composer, conductor and pianist. His work includes two piano concertos, two symphonies and several quartets. His Sensommarnätter ("Late Summer Nights", 1900-1904) includes beautiful episodes of quiet gestures that are sprinkled throughout the piece.
