George Collin Baker (December 21, 1844 - March 23, 1894) was an American inventor and submarine pioneer.
Plans were submitted by Baker, John Philip Holland, Thorsten Nordenfelt and Josiah Tuck.
Holland won the competition, but due to irregularities the contract was not awarded.
Baker nevertheless built his submarine prototype and it was tested in the Rouge River.
[3][4] A new competition was announced in 1893, resulting in rivalry between Holland and Baker, the two inventors with usable vessels.
