Description: Thomas Edison, a native of Milan, Ohio, invented and patented this phonograph. It was Edison's favorite invention. He created what he called the "Speaking phonograph" while working on improvements to Alexander Graham Bell's telephone in 1877. He did not market the machine for another ten years, however, so that he could concentrate on his next invention, the electric light. This oak and metal tabletop phonograph was made between 1915 and 1930 and measures 19.68 by 15.74 by 14.96 inches (50 by 40 by 38 cm). Thomas Alva Edison (1847-1931) was born in Milan, Ohio. He gained fame as an inventor, registering a total of 1,093 patents for such innovations as the incandescent light bulb, the phonograph, and the moving picture camera. View on Ohio Memory.

Description: Two photographs of Charles Kettering's self-starter were taken in the 1960s. Kettering invented the self-starter in 1911, revolutionizing the automobile industry. Prior to Kettering's invention, cars had to be started by hand by turning a large crank in the front of the car. The photographs of the car and self-starter measure 8" x 10" (20.32 x 25.4 cm). Inventor Charles Kettering (1876-1958) was born in Loudonville, Ohio. He registered 140 patents, including the self-starting ignition for automobiles, leaded gasoline, and Freon (with Thomas Midgley Jr.). Kettering founded Delco (Dayton Engineering Laboratories Company) in 1909, where he invented many of his products. Kettering was a 1904 graduate of the Ohio State University. He was also known for his philanthropic work, including the establishment of Sloan-Kettering Institute for Cancer Research near Dayton. View on Ohio Memory.
