Name:
Named in 1980 by Pete J. Dunn, Donald R. Peacor, and Bozidar Darko Sturman in honor of Richard "Dick" Philip Hauck [June 30, 1935 Bloomfield, New Jersey, USA - ] formerly of Bloomfield, New Jersey, USA, and now a resident of Franklin, NJ. Author and co-founder of the Sterling Hill Mining Museum, Ogdensburg, NJ. He is a charter member and a former President of the Franklin-Ogdensburg Mineralogical Society, the Geoliterary Society, and the Franklin Mineral Museum. He is a lifelong, avid collector of minerals, books, and mining memorabilia, especially from Franklin, NJ. His library ranks among the most extensive private libraries in the world dedicated to mining and mineralogy. Pronounced HOW-KITE.
