Thomas Alva Edison, one of the most prolific inventors in history, dies in West Orange, New Jersey, at the age of 84.
Born in Milan, Ohio, in 1847, Edison received little formal schooling, which was customary for most Americans at the time. He developed serious hearing problems at an early age thought to be the result of scarlet fever. Edison, however, believed it was the result of an incident in which he was grabbed by the ears and lifted onto a moving train. His disability motivated many of his inventions. At age 16, Edison found work as a telegraph operator and soon was devoting much of his energy and natural ingenuity toward improving the telegraph system itself. By 1869, he was pursuing invention full-time and in 1876 moved into a laboratory and machine shop in Menlo Park, New Jersey.
Edison’s experiments were guided by his remarkable intuition, but he also took care to employ assistants who provided the mathematical and technical expertise he lacked. At Menlo Park, Edison continued his work on the telegraph, and in 1877 he stumbled on one of his great inventions—the phonograph—while working on a way to record telephone communication. Public demonstrations of the phonograph made the Yankee inventor world famous, and he was dubbed the “Wizard of Menlo Park.ö
Although the discovery of a way to record and play back sound ensured him a place in the annals of history, it was just the first of several Edison creations that would transform late 19th-century life. Among other notable inventions, Edison and his assistants developed the first practical incandescent lightbulb in 1879, and a forerunner of the movie camera and projector in the late 1880s. In 1887, he opened the world’s first industrial research laboratory at West Orange, where he employed dozens of workers to systematically investigate a given subject.
Perhaps his greatest contribution to the modern industrial world came from his work in electricity. He developed a complete electrical distribution system for light and power, set up the world’s first power plant in New York City, and invented the alkaline battery, the first electric railroad, and a host of other inventions that laid the basis for the modern electric world. He continued to work into his 80s and acquired 1,093 patents in his lifetime. He died at his home in New Jersey on October 18, 1931.
