They fired him when he accidentally set fire to the floor of the train. Then Edison worked for five years as a telegraph operator, but he continued to spend much of his time in experimenting his first patent(专利权) in 1868 for a vote recorder run by electricity.

In order to carry on his business, which was to become his life's work, he built a lab at Menlo Park, where he had gone to live. His first great invention was a system of telegraphy (电报学) . Soon afterwards he invented the phonograph (留声机), the first form of the instrument that we now know as the gramophone or record player. The word “phonograph” means something that can “write” or record sound.
