Clark's agent Paul Shefrin said in statement that the veteran host died this morning following a "massive heart attack."
Born in Mount Vernon, N.Y., on November. 30, 1929, Clark pursued his passion at Syracuse University, working as a disc jockey at the student-run radio station while studying for his degree in business. After graduating in 1951, Clark went back to his family's radio station, but within a year, a bigger city and bigger shows were calling.
