John G. Stephenson (1809 in County Armagh, Ireland - 1893 in New Rochelle, N.Y.), an American coachbuilder, invented and patented the first streetcar to run on rails in the United States. Stephenson also designed the New York and Harlem Railroad which was formally opened on 26 November 1832. Twelve days later a horse-drawn streetcar built at Stephenson's works and named John Mason after the president of the railroad company, started the public service. Stephenson is therefore remembered as the creator of the tramway. Stephenson was the great-grandfather of Alan Stephenson Boyd, the first United States Secretary of Transportation.
