James Wilson Marshall was an American carpenter and sawmill operator, who reported the finding of gold at Coloma on the American River in California on January 24, 1848, the impetus for the California Gold Rush. The mill property was owned by Johann Sutter who employed Marshall to build his mill. The wave of gold seekers turned everyone's attention away from the mill which eventually fell into disrepair and was never used as intended. Neither Marshall nor Sutter ever profited from the gold find.
