David Wilkinson (machinist)
David Wilkinson (January 5, 1771 - February 3, 1852)〔http://www.asme.org/Communities/History/Resources/Wilkinson_David.cfm ASME.org bio〕 was a U.S. mechanical engineer who invented a lathe for cutting screw threads, which was extremely important in the development of the machine tool industry in the early 19th century.
==Early life==
David Wilkinson was born at Smithfield, Rhode Island in 1771, the son of Oziel Wilkinson, a skilled blacksmith who moved his family to Pawtucket in the 1780s.
About 1784, his father, Oziel began making anchors in Pawtucket for the emerging shipbuilding industry. The shop was powered by water from the Blackstone River, and was located on the grounds of the present-day Slater Mill Historic Site.
