Kasell's voice, resonant and reassuring, with a lilting trace of his North Carolina tobacco country heritage, helped define NPR as an emerging force in news broadcasting. He joined the public radio network in 1975 and, four years later, helped inaugurate "Morning Edition," writing and reading five-minute top-of-the-hour news updates from pre-dawn to the lunch hour.
