Name:
Named after Frederick and Alice Kraissl, North Hackensack, New Jersey, avid collectors of Franklin, NJ, minerals, former officers of the Franklin-Ogdensburg Mineralogical Society and generous benefactors to the Franklin Mineral Museum. Frederick Kraissl, Jr. [July 8, 1899 New York, New York, USA - November 30, 1986 River Edge, New jersey, USA] was the son of a Croatian immigrant. He earned his masters degree in chemical engineering at Columbia University, New York in 1922 and his PhD, also from Columbia, for his thesis on "The Mechanics of Colors in Gems and Minerals." He was a Practicing Engineer (PE), specializing in the manufacture of glass. Alice Louise Plenty Kraissl [May 5, 1905 - September 16, 1986 River Edge, New Jersey, USA], earned a bachelors degree in engineering from Barnard College in 1925, and co-founded the family business, Kraissl Associates, with her husband. She was an avid micro-mounter as well.
