The Story of Inventions – Frank P Bachman
“The first patent taken out by Edison was in 1869. It was for a vote-recording machine. The machine was designed to secure privacy in voting and to prevent fraud in public elections. The politicians did not want any such machine to come into general use, and the voters were not ready for it, so his first invention proved a flat failure. Edison, however, gained a valuable lesson from this experience. He resolved never to make an invention that was not wanted and that could not be made a commercial success. From that day on, Edison would not begin a project until after he studied with great care the possible demand for it, the cost of making the invention, and the probable profits from its manufacture and sale.” (p.34)
Here are some comments from someone who, I think we’d all agree, was supposed to be the target audience.
