Biography: Linus Yale Jr. was an American inventor and entrepreneur known for his significant contributions to the development of modern locks and keys. He is best remembered for inventing the pin tumbler lock, also known as the Yale lock, which remains a widely used locking mechanism today.

Yale's interest in locks began while working in his father's lock shop, where he developed a fascination with improving existing designs. His most important invention, the pin tumbler lock, patented in 1861, revolutionized the lock industry with its increased security and ease of use.

In 1868, Linus Yale Jr. joined forces with Henry R. Towne to establish the Yale Lock Manufacturing Company, which later became the Yale & Towne Manufacturing Company. The company grew into a global leader in the lock industry, and Yale's designs continue to influence modern lock technology.
