About Thomas A. Edison

Thomas Edison, the American inventor who made his early fortune with the stock ticker and the phonograph record, is credited with inventing the light bulb — although he simply improved upon the original idea by making the bulb burn longer. Edison was born in 1847 in Ohio. He was a dreamer in school; his teacher called him "addled," and his mother taught him at home. He used the money from his inventions to set up a lab with a number of employees; he held a record 1,093 patents in his name. He died in 1931.
