Lock Luster

Tucked into the Midtown Manhattan headquarters of The General Society of Mechanics & Tradesmen of the City of New York is the John M. Mossman Lock Collection. The locks and related items on display, most of which were collected and donated to the museum by Mossman, show the evolution of safe and vault lock technology through the 19th and 20th centuries. The current curator of the locks, John Erroll, describes the collection and its significance.
