In 1893, Elwood P. Haynes purchased a single-cylinder, two-stroke marine engine with the intent to build a car. With the help of the Apperson brothers, the first Haynes-Apperson auto-buggy debuted on the streets of Kokomo, Indiana, on July 4, 1894. In 1898, the Haynes-Apperson Automobile Company was formed and began producing vehicles at the rate of one every two-to-three weeks. By 1901, the relationship between Haynes and the Appersons deteriorated and the partnership dissolved. Haynes continued using the Haynes-Apperson name until 1904, when he simply began calling his cars the "Haynes." In 1905, Haynes presented the original vehicle to the Smithsonian Institution. The Appersons were not mentioned.
