(1744–1816) Revolutionary War engineer and artillery officer, born near Wolverhampton, Staffordshire, England. Machin was best known for the design and installation of a large chain floated across the Hudson River from West Point to Constitution Island (1778). As captain of artillery (1780–83), Machin sighted the first cannon to be fired in the siege of Yorktown (1781). Before joining the Continental army in 1775, Machin had been active early in the Revolutionary cause, belonging to the Sons of Liberty, participating in the Boston Tea Party, and laying out the fortification lines on Bunker Hill.
