Did Edison invent the mimeograph?
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.
Why did Thomas Edison invent the mimeograph?
The first comes from a licensing agreement Edison entered into in 1887 with Chicago-based Albert Blake Dick. Dick was in the lumber business and was tired of writing out the same letters by hand over and over again. He wanted a way to duplicate such materials quickly, and so he invented the Mimeograph machine.
