Captain John H. Hall : ウィキペディア英語版 | John H. Hall (gunsmith)
John Hancock Hall (1781–1841) was the inventor of the M1819 Hall breech-loading rifle, and a mass production innovator. ==Early life== Hall was born in 1781 in Portland, Maine. He worked in his father's tannery until setting up his own woodworking and boat building shop in 1810 where he tinkered with guns in his spare time. He had taken an interest in firearms during militia service and focused on increasing the rapidity of loading.〔Rose, Alexander ''American Rifleman'' (March 2009) pp.51-83〕
