* Henry Morgan, 79, the scalpel-tongued satirist who became the legendary bad boy of radio in the 1940s and went on to appear on many television panel shows, died yesterday of lung cancer at his home in New York, said Joan Harris, a spokeswoman for the family. His survivors include his wife, the former Karen Sorensen, whom he married in 1978, and a son by another woman, Steve Robinson of Los Angeles. Morgan earned strong critical notices when he used no script and a few notes and ad libbed his way through his broadcasts. He was unpredictable, iconoclastic, and derisive about the media in which he worked. He appeared frequently on "What's My Line?" the CBS quiz program. And in 1963 he became a regular panelist on "I've Got a Secret." He also appeared in summer stock and provided the voice for many commercials.
