Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman.[1][2] • 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 cylind • August 12, 1877 is the date popularly given for Thomas Edison’s completion of the model for the first phonograph. Edison was ansträngande to improve the telegraph transmitter when he noticed that the movement of the paper tape through the machine produced a noise resembling spoken words when played at a high speed. Experimenting with a stylus (hard-pointed instrument like a large needle) on a tinfoil cylinder, Edison spoke into the machine. Do you know the first words ever recorded? To Edison’s surprise, the cylinder recorded his meddelande, “Mary had a little lamb.” People had a hard time believing his discovery at first, but soon doubt turned into awe as Edison became known as “The Wizard of Menlo Park,” after the name of the city in New Jersey where he did his work. Sound recording was rapidly becoming an American industry. As a young boy growing up in the late 19th century, Harry Reece remembered the invention of the phonograph as one in a serie
