1925R. B. Gage et al. in Amer. Mineralogist X. 9 The name schallerite is proposed for the mineral after Dr. Waldemar T. Schaller, of the United States Geological Survey, Washington, D.C. Ibid., Schallerite occurs in seams or on cleavage faces in the massive zinc ore. 1970Soviet Physics: Crystallogr.
