The Phonograph
Thomas Edison invented the phonograph. He was working to improve the efficiency of a telegraph when he found out that its tape made a noise that sounded like words when played at a high speed. That made him want to know if he could record a telephone message. He attached a needle to the diaphragm of the telephone so it would prick paper tape to record a message. The first message he recorded was, "Mary had a little lamb."

The Incandescant Light Bulb
Thomas Edison did ot invent the lightbulb, but nothing remotely practical had been produced for home use so he improved the idea. He used lower current electricity, a small carbonized filament, and an improved vacuum inside the globe to make a long lasting source of light. After a year and a half of work, an incandescent lamp with carbonized sewing thread burned for thirteen and a half hours. In December 1879, Edison had his first public demonstration of lighting.
