Carl Adolf Ferdinand Hintze
Ca2[AlF6]F · H2O
Specific Gravity:
Crystal System:
Named in 1979 by Pete J. Dunn, Donald R. Peacor, and B. Darko Sturman in honor of Dr. Carl Adolf Ferdinand Hintze [August 17, 1851 Breslau, Germany {Wrocław, Poland} - December 28, 1916 Breslau, Germany {Wrocław, Poland}], Professor of Mineralogy and director of the Mineralogische Institut, Univerity of Breslau, Breslau, Germany {Wrocław, Poland}. Hintze was acclaimed for his compilation of the famous systematic Handbuch der Mineralogie and particularly for its comprehensive listing of mineral localities.
