- Edison's Autographic Press and Electric Pen, 1875-1880 - Thomas Edison's electric pen, an ancestor of both the mimeograph and the tattoo needle, was a successful product in the mid-1870s. Users would write normally with the pen, which, instead of a nib, had a needle powered by an electric motor. The needle poked holes into a stencil, which was then used to copy the document. Many businesses found document duplication an attractive possibility.

- Edison Rotary Mimeograph, No. 75, 1906-1930 - Thomas Edison received a patent in 1876 for "Autographic Printing," covering the electric pen and flatbed press; a patent for "Autographic Stencils" followed in 1880. The mimeograph was invented by Albert Blake Dick in 1887, who licensed and refined Edison's patents. This low-cost, stencil-based printing technology was popular until displaced by photocopying machines and offset printing in the 1960s.

- Edison Electric Runabout, circa 1889 - Thomas Edison had this car built about 1889 to investigate electricity as a power source for automobiles. The three-wheeled vehicle has two electric motors, each separately connected to one of the front wheels. Having successfully operated the car, Edison put it aside for several years. He reactivated the runabout in 1905 to test experimental nickel-iron alkaline batteries.
