Name:
Named in 1974 by Paul Brian Moore and Jun Ito in honor of Willard "Bill" Lincoln Roberts [February 12, 1923 Epworth, Iowa, USA - March 23, 1987 Rapid City, South Dakota, USA], professor of mineralogy and curator of the South Dakota School of Mines mineral museum. Bill was strongly influenced by the phosphate mineral bearing granite pegmatites of the nearby Black Hill and collaborated with many mineralogists, including Mary Mrose, Paul Moore, and Jun Ito and through this collaboration about 15-20 phosphates minerals were described by various authors. Bill was senior author of both the Mineralogy of the Black Hills and the Encyclopedia of Minerals (first edition).
