He was one of the first people to use the Detroit Free Library. He went through the library reading asmany books as he could. He spent much of his time reading books on electricity, mechanics, chemical analysis, manufacturing, and technology (www.minot.k12.nd.us/mps/edison.html).

While Edison was at the train station he learned to use the telegraph from one the station officials. He used scrap metal to build a telegraph set and practiced Morse code. When he was sixteen he moved to Toronto, Canada, to become a telegraph assistant. His job was to report in every hour by telegraph signal. Edison thought that this was a waste of time, so he invented an automatic telegraph. Thomas moved back to the U. S. and worked as a roaming telegrapher.
