He paid the brothers, Elmer and Edgar Apperson, forty cents an hour to build the car from his diagrams. After it was built and successfully tested, the Appersons and Haynes created a corporation to build cars until 1902. Haynes went on to invent the muffler and different metal alloys. His most important invention was probably stellite alloy, which opened the door to the development of a series of space age alloys of the highest melting temperatures, taking the greatest stress, and virtually eliminating corrosion. In 1967, the Elwood Haynes Museum was established in a small mansion in Kokomo, where Haynes had lived the last years of his life until 1925.
