Discussion Questions

  1. In your opinion, what drew young Edison to telegraphy?
  2. Why were Congressmen opposed to the electronic vote counter? How did their response effect Edison's goals?
  3. Why were Edison's laboratories in Menlo Park and West Orange so innovative in their concept as well as their products?

Research Projects

  1. Alexander Graham Bell began his career working with the hearing impaired, while Edison himself had severe hearing problems. In a short poem or essay, imagine why these men invented devices that promoted communication.
  2. Draw a diagram of Edison's original cylinder phonograph which explains how it works.
  3. Edward Gilliland, originally a close friend of the inventor, worked hard on improving Edison's phonograph. Eventually, both men felt betrayed by the actions of each other. Research this story to explain the improvements added by Gilliland . Investigate the questions of loyalty raised by each man's attitude and response. Present your findings in a paper or on a chart.
