70030 Margaretmiller           Discovered 1999 Feb. 7 by B. D. Warner at Palmer Divide Observatory.
Margaret Joan Miller (b. 1956) is the wife of the discoverer. A graduate of Indiana University, she is an accomplished violist who, as a member of the DaVinci Quartet, was a prize winner in two major international competitions. She now devotes her time to teaching viola and violin to students of all ages.
