It did not sell so thereafter he decided to concentrate his efforts on inventions that he was sure would be in universal demand. Then in 1869 Edison arrived in Boston, he persuaded a broker to let him sleep in his office. Then when the broker’s stock ticker broke Edison was able to repair it where many others had failed. Amazed the manager quickly made Edison one of his superiors.
