Yale is one of the oldest international brands in the world and one of the best-known names in the locking industry. The Yale history captures major innovations that have marked the evolution not just of Yale, but of the entire locking industry.
Linus Yale Sr.'s son perfected and patented his father's pin tumbler cylinder lock and became the considered locking expert of his time. In 1862, Linus Yale Jr. introduced the Monitor Bank Lock, marking the transition in bank locks from key locks to dial or combination locks. The principles, embodied in his Monitor Lock, are now standard in combination locks throughout the USA.
