Thomas Edison (1847-1931) was a legendary figure in his lifetime, and even decades after his death he is considered one of history's most significant inventors. Edison's enduring achievement in this realm was tied to the incandescent light bulb, but he also came up with a safe, efficient way to deliver the power that lit those bulbs. It ushered in a new era, changing the way the modern world lived, worked, and played. He also made improvements to the telephone invented by Alexander Graham Bell (1847–1922), devised the first working phonograph, and made important scientific contributions to the early motionpicture industry. His accomplishments in the final two decades of the 19th century were so valuable that the period was once commonly called the "Age of Edison" in school history books for many years.
