The Elwood Haynes Museum is a museum in the former mansion Elwood Haynes, an inventor who is credited with being the first to produce cars commercially in 1894. He also invented stainless steel and stellite. He became a millionaire in 1916 and purchased the mansion located on Webster Street in Kokomo, Indiana in the same year.
The mansion was sold by March Haynes to General Motors who used the building as a residence for traveling executives for several years. GM sold the building in 1965 and it was purchased by Bernice Haynes who donated it to the city of Kokomo. Since 1967 it has been open to the public and the museum curators have collected many of Haynes original inventions to display in the building. The museum features exhibits on the life of Haynes and is open the public who can tour the building.
