Name:
Named by Fred Eugene Wright in 1908 in honor of William Francis Hillebrand (12 December 1853, Honolulu, Hawaii, USA - 7 February 1925, Washington, D.C., USA). Hillebrand was regarded as one of the best wet analytical method chemists in the USA and was with the U.S. Geological Survey. He described 5 new minerals himself, and 11 others jointly.
White fibrous crystals typical. Compare 'UM1977-14-SiO:CaH'.
