Bogardus, JAMES

Bogardus, JAMES, American inventor, born in Catskill, New York, 14th March 1800, was apprenticed to a watchmaker, and early showed the bent of his mind by improvements in the construction of eight-day clocks, and by the invention of a delicate engraving-machine. The dry gas-meter is his invention, as is also the transfer-machine to produce bank-note plates from separate dies; and in 1839 his plan for manufacturing postage-stamps was accepted by the British government. Later he introduced improvements in the manufacture of india-rubber goods, tools, and machinery; and invented a pyrometer, a deep-sea sounding-machine, and a dynamometer. He died at New York, 13th April 1874.
