The John M. Mossman Lock Collection represents one of the most complete anthologies of bank and vault locks in the world, with more than 370 locks, keys and tools dating from 4000 BC to the modern 20th-century. Many of the examples are unique, made-to-order locks that were not produced in commercial quantities and nearly every lock has protected millions in money and securities.

To augment the lock collection. Mr. Mossman donated his notes and scrapbooks, known as the Mossman papers, which have proven to be a valuable resource for the study of locks. “The Lure of the Lock” was published in 1928 and describes each lock in the collection.
