Gilbert Henderson Harrington (born April 17, 1845 - died June 22, 1897) was the main founder of the arms manufacturing firm of Harrington & Richardson.
Harrington was the son of Henry Henderson Harrington and Cornelia Bush Wesson. Born at Shrewsbury, Massachusetts, they later moved to Worcester, Massachusetts when he was a child.
Frank Wesson started a firearms manufacturing firm in 1859, sharing an early patent with Nathan Harrington. Wesson produced two trigger rifles and spur trigger pistols and pocket rifles/shotguns popular for short length holster models such as the discontinued topper compact pocket shotguns. He started a brief partnership in 1871 with his nephew Gilbert Henderson Harrington, as Wesson & Harrington, until Harrington bought him out in 1874.
