Snider
Snider, JACOB, born in 1820, started in business as a wine merchant, but failed. He then devoted himself to mechanical inventions, and in 1859 came over to Europe with a model of the Mount Storm breech-loader, made by converting the muzzle-loading rifle of the United States army. His modified plans were at last accepted by the English War Office for the conversion of the Enfield rifle, and the new weapon was known by the inventor's name. Endless disputes then followed as to his remuneration, till, crushed by poverty and disappointment, he died in 1866 before he got his claims recognised.
