Thomas Edison

Died 18 Oct 1931 at age 84 (born 11 Feb 1847). Thomas Alva Edison was an American inventor who held a world record 1,093 patents (including those held jointly) and created the world's first industrial research laboratory. He showed an early curiosity for explanations of how everything worked and was especially interested in chemistry. He began selling newspapers on the railroad at age 12, and learned how to operate a telegraph. In 1868, his first invention was an electric vote-recording machine. In 1869, he made improvements on the stock-ticker. In 1876 he moved his laboratory to Menlo Park, N.J., where he invented his phonograph (1877) and the first prototype of a commercially practical incandescent electric light bulb (1879). Other inventions included storage batteries, a dictaphone, and a mimeograph. By the late 1880s he made motion pictures, and by 1912 was experimenting with talking pictures. Edison developed electric power from central generating stations. He became known internationally as “the Wizard of Menlo Park.”In 1962 his second laboratory and home in West Orange, New Jersey, was designated a U.S. National Historic Site.
