Named in honor of Andres Bernardus Muller, astronomer at the Leiden Observatory and leader of the site-testing campaigns for the European Southern Observatory in South Africa and Chile. From 1964 to 1969 he was superintendent at La Silla {see planet  (2187)} while ESO was under construction. He was involved with instrumental improvements at ESO, especially for the 1-m Schmidt telescope, with which this minor planet was discovered. (M 27124) _ _.
