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.
