In 1885, Thomas Edison wrote, "I have not heard a bird sing since I was twelve." No one is really sure just how Edison lost most of his hearing. Yet this man invented the first machine that could capture sound and play it back. In fact, the phonograph was his favorite invention. The first phonograph was invented in 1877 at the Menlo Park lab. A piece of tin-foil was wrapped around the cylinder in the middle. You shouted a short message into the piece on one side of the cylinder while you turned the handle. Inside this piece was a needle. Your voice would make the needle shake, or vibrate. The sound vibrations would go through the needle and make a line, or groove, into the tin-foil. A needle on the other side could play back what you had just recorded. After just a few plays, the tin-foil would tear up and the message could no longer be played. That is why the tin-foil recordings cannot be played anymore. Later phonographs played records. The first ones were in the shape of a cylinder, with the music on the outside. Later records were shaped like discs, or large CDs. Edison loved the phonograph so much that he called it his "baby". He improved it over and over for the next fifty years.

The success of his electric light brought Edison to new heights of fame and wealth, as electricity spread around the world. Edison's various electric companies continued to grow until in 1889 they were brought together to form Edison General Electric. Despite the use of Edison in the company title however, Edison never controlled this company. The tremendous amount of capital needed to develop the incandescent lighting industry had necessitated the involvement of investment bankers such as J.P. Morgan. When Edison General Electric merged with its leading competitor Thompson-Houston in 1892, Edison was dropped from the name, and the company became simply General Electric.
This period of success was marred by the death of Edison's wife Mary in 1884. Edison's involvement in the business end of the electric industry had caused Edison to spend less time in Menlo Park. After Mary's death, Edison was there even less, living instead in New York City with his three children. A year later, while vacationing at a friends house in New England, Edison met Mina Miller and fell in love. The couple was married in February 1886 and moved to West Orange, New Jersey where Edison had purchased an estate, Glenmont, for his bride. Thomas Edison lived here with Mina until his death.
