Thomas Alva Edison is the Greatest American, because he invented the phonograph. The phonograph was a rotating disk that allowed sound vibrations to be recorded. According to Resource Center- Gold, at the start of Thomas’s invention of the phonograph Thomas saw “no application for the phonograph.” Then Edison sat the phonograph aside for a very long time. Based on Josephson thoughts from the article from Student Resource Center- Gold Thomas had “abandon research on the phonograph.” In 1877, Thomas made his favorite invention which he named the phonograph. Thomas’s very first model of the phonograph could transfer sound vibrations. Although the first model lacked good quality, it produced really good sound. The discovery of the phonograph reached quickly around to people. The phonograph was a very simple, and a mechanical device. From an instrument replaying sounds, the phonograph became a machine playing records by 1887.According to Student Resource Center-Gold," by 1890, he had more than 80 patents on it.” The phonograph was one step closer to the invention the ediphore. The ediphore used disks rather than foil or waxed records. Edison presented the phonograph at the Royal Institution in London. Edison also went to the White House to present the phonograph to President Rutherford B. Hayes. Without the invention of the phonograph inventors would’ve never gotten the idea create such devices as the tape recorder or the video camera. The phonograph allowed people to save important messages and songs. Also without the invention of the phonograph music couldn’t be heard or couldn’t get around to others to hear. To tell you the truth most of Thomas’s fame came from his invention of the phonograph.

I did not know that the first thing Thomas Edison ever invented was the phonograph.
