FRONTIER GUARDIAN observes that "Mr. Jonathan Browning is manufacturing some of the most splendid revolving rifles that we ever saw." He invents one of "the earliest known American repeating rifles" when he moves to Nauvoo in 1842. Establishes gunsmith shop in Ogden, Utah where he continues making his unpatented "six-shot repeater." His son John M. Browning is "the father of modern firearms."
