Name:
Named in 1957 by Clifford Frondel in honor of Karl Hugo Strunz [February 24, 1910 Weiden in Oberpfalz, Bavaria, Germany - April 19, 2006 Unterwössen, Bavaria, Germany], Professor of Mineralogy, Technische Universität, Berlin, Germany. Strunz was a systematic mineralogist and published on classification of silicate mineral crystal structures in 1937 (in the same year as Harry Berman), as well as a complete mineralogical classification, notably in successive editions of Mineralogische Tabellen, the first of which was published in 1941. Strunz's classification is based on both chemistry and crystal structure. He was one of the founders of the International Mineralogical Association. Strunz was particularly interested in phosphate minerals from granite pegmatites and Clifford Frondel doggedly pursued trying to acquire enough mineral in order to name a mineral for Dr. Strunz. Frondel made an appeal to every mineral field collector he came in contact with to provide as much of a tiny acicular mineral as they could. Strunzite was informally known as "Frondel's whiskers", before it was formally named. Because of Frondel's "crowd finding" method, the initial description of strunzite was made on specimens from a wide variety of locations. Strunz was also an active describer of new mineral species, particularly from Hagendorf, Germany and Tsumeb, Namibia. He named chudobaite, fleischerite, hagendorfite, itoite, laueite, liandradite, petscheckite, pseudolaueite, stranskiite, and five other species.
Strunzite Group. Related to the lower hydrate, laueite. Compare zincostrunzite.

(TL) - Type Locality for a valid mineral species. (FRL) - First Recorded Locality for everything else (eg varieties). Struck out - Mineral was erroneously reported from this locality. Faded * - Never found at this locality but inferred to have existed at some point in the past (eg from pseudomorphs.)

All localities listed without proper references should be considered as questionable.
