Founded in Providence, Rhode Island, in 1831, by Jabez Gorham in partnership with Henry L. Webster. Their main product was silver spoons, plus thimbles, combs and jewelry. When Jabez retired in 1847, the business was run by his son John Gorham. They merged with Black, Starr & Frost in 1929 to become Black, Starr & Frost & Gorham and subsequently Black Starr & Gorham, which lasted from 1940 though to 1962. The company changed hand several times after that, but is now part of the Lenox Inc. group.
