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. 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.[2] Nick Gartner became the manager of new product development for S&G in 1970. He patented the first electronic safe lock.[3] 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.
