(4571) Grumiaux Main-belt Asteroid

Discovered on 8 September 1985 by H. Debehogne at La Silla.

Named in memory of Arthur Grumiaux (1921–1986), Belgian violinist who established the conservatories of Charleroi and Brussels. After winning the Vieuxtemps Prize in 1939 he went to Paris to study with Georges Enesco. Of particular brilliance are his recordings of the Mozart and Beethoven sonatas with Clara Haskil at the piano and of Bach's sonatas and partitas for unaccompanied violin. His superb renditions of Mozart's music will last for ever. Name proposed in consultation with E. Goffin, who found the identifications involving this minor planet.Naming citation (WGSBN Bull. 4, #11, 5), IAU / Minor Planet Center, via NASA/JPL
