About FrankliniteHide

Metallic, Sub-Metallic
5½ - 6
Specific Gravity:
5.07 - 5.22
Crystal System:
Named in 1819 by Pierre Berthier for the type locality of Franklin Furnace (now Franklin Borough), New Jersey. Silliman (1920) translated Berthier's article: "As the chemical nomenclature cannot in every instance furnish a name, I propose to give it that of The Franklinite, in order to remind us that it was found, for the first time, in a place to which the Americans have given the name of a great man, whose name is equally venerated in Europe as in the new world by all the friends of science an humanity."

Benjamin Franklin [January 17, 1706 Massachusetts Bay Colony - April 17, 1790 Philadelphia, Pennsylvania, USA], American statesman, was also the first important USA scientist who investigated electricity and was an inventor of bifocal lenses for eye glasses, the fuel efficient Franklin Stove, lightening rods, the carriage odometer, and the glass harmonica (musical instrument). He was was co-founder of the University of Pennsylvania and the American Philosophical Society as well as serving as Governor of Pennsylvania. He established the model for volunteer fire fighting services. He was the first postmaster of the USA and devised an efficient postal delivery system. He was an important early abolitionist. As a genuine polymath, he was an author and philosopher, newspaper editor, but he is primarily celebrated as a politician and ambassador and credited as a Founding Father of the United States of America.
