“ PERKINS, JACOB (1766–1849) , American inventor and physicist, was born at Newburyport, Massachusetts, in 1766, and was apprenticed to a goldsmith. He soon made himself known by a variety of useful mechanical inventions, and in 1818 came over to England with a plan for engraving bank-notes on steel, which ultimately proved a signal success, and was carried out by Perkins in partnership with the English engraver Heath. ”
