D. Whit (D. W.) Colvin[i] (July 24, 1874 - November 5, 1933) was an American inventor who claimed several attempts at the manufacture of perpetual motion machines. The most infamous was the Colvin spring motor, which became the focus of U.S. national press and federal court attention when Colvin was arrested on fraud charges in 1921, the device described as "a contrivance of a wheel, a disk and a spring, which would go around for sometime," though apparently not indefinitely. After his trial concluded and Colvin was released from incarceration, he continued in his efforts to produce a workable self-motive motor until his death.

  1. Newspapers covering Colvin's 1921 fraud case give his name variously as D. W. Coleman, D. W. Caldman, George W. Coleman, D. V. Colvin, &c. In other sources, his personal name is sometimes given as D'Whit rather than D. Whit; it is unclear what, if anything, the D. stood for.
