Harold Wampler Arlin (December 8, 1895–March 14, 1986) was an American engineer and foreman and was arguably the world's first full-time and salaried announcer in broadcast radio. Arlin originally worked as an engineer and later foreman for the Westinghouse Electric and Manufacturing Company when he was hired as a part-time announcer by KDKA, the nation's first commercially licensed radio station, in Pittsburgh in 1920. On November 2, 1920, Arlin made history as the radio's first announcer when he read over-the-air the returns to the 1920 presidential election between Senator Warren G. Harding and Governor James M. Cox.
