Mr. Obama’s lesson about the 19th president seems wrong, at least according to historians at the Rutherford B. Hayes Presidential Center in Fremont, Ohio. Hayes “was very technologically savvy,” said Nancy Kleinhenz, the communications manager at the Rutherford B. Hayes Presidential Center. In addition to being the first president to have a telephone in the White House, he was also the first president to use the typewriter, experiment with the phonograph and record his voice on Thomas Edison’s gramophone.
