Carl Fisher, born in Greensburg in 1874, was an entrepreneur who helped make automobiles a viable form of transportation. In 1904 he co-founded Prest-O-Lite Co., which developed acetylene gas vehicle headlights distributed nationwide. He was also co-founder and president of Indianapolis Speedway, site of the famous annual 500 mile race and a testing ground for new automobile technology. A proponent of the Good Roads Movement, Fisher advocated construction of U.S. transcontinental roads including the east-west Lincoln Highway in 1912 and the north-south Dixie Highway in 1914, roads that enabled long-distance travel by automobile. He also developed Miami Beach into a major resort destination, and he died on July 15, 1939.
