9468 Brewer           Discovered 1998 June 1 by E. W. Elst at the European Southern Observatory.
Named in honor of James Brewer, ESO astronomer working on stellar populations and carbon stars. Using intermediate band photometry, he has identified C- and M-type stars in M31 and demonstrated that the ratio of these stars tracks the metallicity gradient in the disk. He is currently working on the globular clusters of the Fornax dwarf spheroidal galaxy. During 1998 he was of great help to the discoverer in obtaining observations with the ESO Schmidt.
