Henry Newton Brown (1857 – April 30, 1884) was an American Old West gunman who played the roles of both lawman and outlaw during his life. Brown was raised in Cold Springs Township, in Phelps County, ten miles south of Rolla, Missouri. An orphan, he lived there with his uncle Jasper and aunt Aldamira Richardson until the age of seventeen, when he left home and headed west. He drifted through various cowboy jobs in Colorado and Texas, supposedly killing a man in a gunfight in the Texas Panhandle.
