Arnold Zenker Is CBS TV's Forgotten News Anchor

Scott Pelley and Arnold Zenker

Fifty years ago this month, AFRTA, the union representing Radio and  TV personalities, had called a walkout.

Some of the most famous TV faces of the day, including “What’s My Line” host John Daly, were off the air and on the street.

And the list included longtime “CBS Evening News” anchor Walter Cronkite.

Newscasters were replaced by management. But who would sub for Cronkite?

An A-to-Z search led to Arnold Zenker, a 28-year-old CBS News executive, who had worked his way through school doing radio broadcasts.
