Name:Named in 1929 by Lawson H. Bauer and Harry Berman in honor of miner and mineral collector, Samuel R. Losey [December 10, 1830 New jersey, USA - July 26, 1904 USA], of Franklin, New Jersey, USA. Frederack A. Canfield, Jr. briefly mentioned some of his family's 19th century sources for Franklin District minerals: "More Franklin minerals were collected by Samuel Woodruff than by both miners of the Losey family and by the several miners of the Kemble family."
