What was the make of the first American automobile?

The first production automobile in the United States on record was the Duryea Motor Wagon Company. Brothers Charles and Frank Duryea demonstrated their first automobile September 21, 1893 in Chicopee, Massachusetts. In 1895 they began commercial production and sold 13 cars by the end of 1896. Duryea would produce automobiles until 1917 under the guidance of Charles since Frank left the company to produce cars at Stevens-Duryea after a disagreement with his brother. The previous answer of Ford is incorrect as Henry Ford did not produce an automobile until his 1898 prototype in which he left the Edison Illuminating Company as an engineer to found the Detroit Automobile Company on August 5, 1899.
