5961 Watt           Discovered 1989 Dec. 30 by R. H. McNaught at Siding Spring.
James Watt (1736-1819) was a Scottish engineer whose improvements to the steam engine led to the rapid advances of the industrial revolution. The SI unit for power, the watt, is named in recognition of his development of the concept.
