History
The James Sargent Lock Company was founded in 1857 by James Sargent.[1] In 1865, Sargent partnered with a Halbert Greenleaf, a former employer. The company was renamed to Sargent & Greenleaf and began operations in Rochester, NY. In 1869 the company got the first of many government contracts to design and produce safe locks for the U.S. Treasury Department.[2] During World War I and II they produced a wide variety of builder's hardware as well as many lock and safe designs.
Harry C. Miller began working for S&G at the end of World War II, and in 1953 became the president and owner.[3] Nick Gartner became the manager of new product development for S&G in 1970. He patented the first electronic safe lock.[4] He left to form his own company La Gard in 1974, and S&G relocated to their current home of Nicholasville, Kentucky. In the late 1980s Sargent & Greenleaf began producing a variety of high-security padlocks for the U.S. government. Among these designs were the S&G 831 and S&G 833 models that use Medeco cylinders. Production of the popular 6120 electronic combination lock series began in 1993.
In 2005, Sargent & Greenleaf was acquired by Stanley Black and Decker, Inc., an international tool and hardware manufacturer. S&G was acquired by OpenGate Capital, a private equity firm, in 2019.
