The legend of Thomas Edison shines a little dimmer, thanks to researchers at Lawrence Berkeley National Laboratory who have played a 10-second recording of a woman singing made in 1860--17 years before Edison received a patent for the phonograph. The recording was made by Édouard-Léon Scott de Martinville, a Parisian typesetter and inventor, on a device known as a phonautogram, which captured sounds and recorded them on paper.

The second article discusses why some inventors become legends and others fade into obscurity. As it turns out, many of the inventions, such as the telephone, radio and light bulb, that are attributed to single inventors were actually developed independently by several individuals.
