Stevens Arms was an American firearms manufacturer founded by Joshua Stevens in 1864 in Chicopee Falls, MA.  The company introduced the .22 Long Rifle round and made a number of rifle, shotgun, and target pistol designs.  By 1902 they were advertising themselves as "the largest producers of sporting arms in the world".  They were purchased by New England Westinghouse on May 28, 1915 and again by Savage Arms on April 1, 1920.  As a  subsidiary division of Savage, Stevens continued to produce firearms at their Chicopee Falls facility until 1960, but in a semi-independent status until 1942 .  That plant was torn down in n1960 and the Stevens production was moved into other Savage facilities.  Savage dropped the Stevens name in 1991 but revived it in 1999 and still uses it today for a number of its low cost rifles and shotguns.
