Name:
Named in 1984 by Donald R. Peacor, P. J. Dunn, William B. Simmons, E. Tillmans, and R. X. Fischer in honor of William "Bill" A. Henderson Jr. [October 5, 1932 Winthrop, Massachusetts, USA - April 20, 2014 Guilford, Connecticut, USA], chemist with American Cyanamid Company of Stamford, Connecticut (USA). In late 1980, Dr. William A. Henderson, Jr. submitted a specimen to P.J.D. that he had obtained several years earlier from Mr. Gianni Porcellini of Rimini, Italy. Bill was an avid life-long mineral collector and columnist for the Mineralogical Record. He was elected as a member of the Micromounters Hall of Fame in 1997.
