Rollin White

Rollin White (June 6, 1817 – March 22, 1892) was an American gunsmith who invented a single shot bored-through revolver cylinder that allowed paper cartridges to be loaded from the rear of a revolver's cylinder. Because the open breeches were unprotected from lateral fire, all charges would instantly explode in a chain fire. Only one gun would be built to White's specifications, and that for use in a trial to show the impracticality of the gun. The gun could not fire metallic cartridges.
