He had his grandmother add some fur at the ends of a piece of wire. He received patent #188,292. His invention became a factory, employing community members.
First telephone in White House was installed in 1877. President Rutherford B. Hayes had the phone placed in the telegraph room. Few people had phones, so the phone seldom rang. Its phone number was “1.” President Herbert Hoover had a telephone installed in the Oval Office on March 29, 1929.
