Named in honor of Robert W. L. Simpson, English composer, who has celebrated his 70th birthday in 1991. Simpson’s musical character has been mainly expressed in his symphonies and string quartets, which are influenced by Beethoven, Bruckner and Sibelius {which are also present at the minor planet sky with numbers (1815), (3955), and (1405)}. The discoverer has long regarded Simpson as one of the greatest musical structuralists. An astronomer by avocation, Simpson is a fellow of the Royal Astronomical Society. (M 18465) _ _.
