Thomas Edision and the Phonograph, every American boy and girl has Edison's name closely associated with the brilliant little globes of light, which are seen by thousands along city streets, in churches, in theaters, in public halls, and even in private dwellings. A traveler in far off Egypt asked an ignorant donkey boy if he had ever heard of the President of the United States. He next asked if he had ever heard of Edison. With a nod of intelligence, the boy pointed to the electric light before the door of the hotel for answer. Edison once said that the electric light had cost him more time, anxiety, and expense than any other invention. It was, however, the invention, which made him independently rich.

There are very few departments of electrical invention to which he has not contributed something. The electric railroad and the automobile have received a share of his thought. His telephone; the megaphone, which carries the sound of the voice great distances without the help of wires; the quadruplex telegraph; the tasimeter, which measures the heat of the stars; or the kinescope, - any one of them would have made the inventor famous.

Some twenty-five thousand notebooks contained his research records, ideas, hunches, and mistakes. Edison died in West Orange on October 18, 1931. The laboratory buildings and equipment associated with his career are preserved in Greenfield Village, detroit, michigan, thanks to henry ford's interest and friendship.

In 1908 his cinema-phone appeared, adjusting film speed to phonograph speed. In 1913 his kinetophone projected talking pictures: the phonograph, behind the screen, ran in time with the projector through a series of ropes and pulleys. Edison produced several "talkies.". Work for the government, during World War I (191418) Edison headed the. Navy consulting board and contributed forty-five inventions, including substitutes for previously imported chemicals, defensive instruments against U-boats, a ship telephone system, an underwater searchlight, smoke screen machines, antitorpedo nets, navigating equipment, and methods of aiming and firing naval guns.

The Edison battery was perfected in 1910. After eight thousand trials Edison remarked, "Well, at least we know eight thousand things that don't work.". Edison's motion picture camera, the kinetograph, could photograph action on fifty-foot strips of film, sixteen resume images per foot. In 1893 a young assistant, in order to make the first Edison movies, built a small laboratory called the "Black maria"—a shed, painted black inside and out, that revolved on a base to follow the sun and keep the actors visible.

Many towns and cities installed central stations based on this model. Increased use of electricity led to numerous improvements in the system. In 1883 Edison made a significant discovery in pure science, the Edison effect—electrons (particles of an atom with a negative electrical charge) flowed from incandescent conducting threads. With a metal plate inserted next to the thread, the lamp could serve as a valve, admitting only negative electricity.

Although "etheric force" had been recognized in 1875 and the Edison effect was patented in 1883, the discovery was little known outside the Edison laboratory. (At this time existence of electrons was not generally accepted.) This "force" underlies radio broadcasting, long-distance telephone systems, sound pictures, television, x rays, high-frequency surgery, and electronic musical instruments. In 1885 Edison patented a method to transmit telegraphic "aerial" signals, which worked over short distances. He later sold this "wireless" patent to guglielmo marconi (18741937).

Edison and his staff examined six thousand organic fibers from around the world, searching for a material that would glow, but not burn, when electric current passed through. He found that Japanese bamboo was best. Mass production soon made the lamps, while low-priced, profitable.
