Ben Lyon, 77, a Hollywood star in the 1930s and later a popular radio and television personality in Britain, died Thursday aboard the ocean liner Queen Elizabeth II, after apparently suffering a heart attack.

He was stricken while the liner was on its way from Honolulu to Long Beach, Calif. Mr. Lyon had been performing aboard the ship. With him was his second wife, the former Marion Nixon.

Mr. Lyon and his first wife, Bebe Dianiels, who died in 1971, had successful film careers in Hoolywood during the 1930s.

He appeared in such films as the classic "Hel's Angels," and "I Cover the Waterfront," "Flying Machine," "Hat Check Girl" and "Dancing Feet,"

He and Miss Daniels were appearing at the Palladium in London when World War II broke out and they decided to stay in England. After this country entered the war, Mr. Lyon enlisted in the U.S. Air Force. He continued to broadcast a popular radio program during the air raids on London. He later was decorated by Queen Elizabeth II.

He and Miss Daniels had a radio whow, "Hi Gang," and then a radio and a television show called "Life with the Lyons."

After the war Mr Lyon divided his time between London and Hollywood and at one time a casting director with 20th Century Fox. He suggested that a budding starlet named Norma Jean Baker take the name of Marilyn Monroe.

Mr. Lyon and his wife had been living in the Beverly Hills area.

Also surviving are two children of his first marriage, Richard and Barbara, who live in England. CAPTION: Picture, BEN LYON
