Howard Andrew Williams was born on Dec. 3, 1927, in Wall Lake, Iowa, a small town northwest of Des Moines. His father, Jay, a railroad company mail clerk who later went into the real estate and insurance businesses, and his mother, the former Florence Finley, had one daughter and five sons, Andy being the fourth. “The Andy Williams Show” ran on NBC from 1962 to 1971 and won three Emmy Awards for outstanding variety series. On a 1991 visit to Branson, the small Ozark Mountains town that had become an entertainment vacation destination, Mr. Williams decided to build a theater there. When the 2,000-seat Andy Williams Moon River Theater opened the next year, it was Branson’s first non-country-music attraction. He performed there several months a year until last November. He also had a home in La Quinta, Calif. Mr. Williams married Claudine Longet in 1961, and they had two sons, Christian and Robert, and a daughter, Noelle. The couple divorced in 1975. That year Ms. Longet was charged with fatally shooting Spider Sabich, a ski racing champion, in Aspen, Colo. Mr. Williams stood by his ex-wife, who contended that the shooting was accidental, and accompanied her to court during her trial. She was found guilty of criminally negligent homicide, a misdemeanor, and sentenced to 30 days in jail. In 1991 Mr. Williams married Debbie Haas, a hotel executive. She survives him, as do his children, his brothers Don and Dick, and six grandchildren.
