Linus Yale

Linus Yale, inventor of a popular and effective lock that uses a pin-tumbler cylinder design, was born in Salisbury, New York, on April 4, 1821. As a youngster, Yale possessed a great deal of mechanical skill and ingenuity. His father, Linus Yale Sr., was a successful inventor, having created sawmill head blocks and a millstone process. The older Yale was also interested in new lock designs, and spent much of his time on bank locks. In the 1940s he created one of the first modern locks that used a pin-tumble design. He opened the Yale Lock Shop in Newport, Rhode Island, in 1847.

The younger Yale, meanwhile, who was artistically talented, had begun serious studies in portrait painting. In 1850 he decided a career in painting wasn’t for him and began devoting time to mechanical problems. His father died sometime around this period and Yale became more involved in his father’s lock shop. Eventually he set up his own lock business in Shelburne Falls, Mass. He had become convinced that keyholes in traditional locks made the locks susceptible to thieves who could use picks,

Linus Yale, Jr.

Linus Yale, Jr. (1821 – 1868) was born in Salisbury, NY, on April 4, 1821, to inventor Linus Yale, Sr., whose ancestors immigrated to the New World in colonial times from North Wales. The creator of sawmill head blocks and a millstone process, Linus Sr.'s, real passion was locks, particularly those used in banks. From that interest and hours of tinkering came one of the first modern locks to use a pin-tumble mechanism, which could be traced back to the large wooden locks the ancient Egyptians built some 4,000 years ago. After receiving a patent for his design, Yale, Sr. went on to specialize in high-security bank locks, which he sold through the Yale Lock Shop he founded in Newport, NY, in 1847.

While his son Linus would one day go on to follow in his father's footsteps, the young Yale spent his early adulthood indulging his interest in painting, hoping one day to become a respected portraitist. He gave up that dream in 1850 when Linus, Sr. died, and decided to go into the family business, first tending his father's lock shop then opening up
