Harold Wampler Arlin (1895–1986) was an American engineer who became the world's first full-time, salaried broadcast radio announcer when he was hired by Pittsburgh's KDKA, the first commercially licensed station, in 1920. He made history on November 2, 1920, by reading the returns of the presidential election between Warren G. Harding and James M. Cox over the air from a makeshift shack on a Westinghouse plant roof. Arlin pioneered sports broadcasting, announcing the first-ever radio broadcasts of a baseball game (Pirates vs. Phillies on August 5, 1921, using a converted telephone as a microphone), as well as the first tennis, football, and boxing matches. Nicknamed the "Voice of America", his voice reached listeners on several continents, with The London Times calling him "the best known American voice in Europe." During his five years at KDKA, he interviewed celebrities like Babe Ruth and Will Rogers, cementing his legacy as a foundational figure in broadcast media.
