Yale & Towne Manufacturing Co, 1897. In 1868, the business was established in Stamford, Connecticut, by Henry R. Towne and Linus Yale Sr., an inventor renowned for creating the pin tumbler lock. Initially known as Yale Lock Manufacturing Co., the company later adopted the name Yale & Towne, with its base in Newport, New York. [3]
The first known example of a tumbler lock was found in the ruins of the Palace of Khorsabad built by king Sargon II (721–705 BC.) in Iraq.
