Although it's probably of little interest to the membership, but in the interest of maintaining accuracy I'll mention that Genth first described genthelvite in 1892 but did not recommend a name. Genth's description appears in Am. Jour. Sci., 44, 385 (1892). Glass, et.al., named the mineral after Genth in the reference listed on the genthelvite descriptive page - Am. Min., 29, Nos. 3 & 4, 163-191 (1944).
Perhaps one of you gentlemen could clear up some question on the pronunciation of the mineral. Most people pronounce it "genth - elvite," but I maintain it should be "gent - helvite" for two reasons. First, the name "Genth" would be pronounced "Gent" in the original language, and second, genthelvite is a member of the helvite group of minerals, so the "h" must be pronounced. Comments?
