The news that Betty McGuire dies at 100 has prompted renewed appreciation for an actress whose career reflected the changing eras of entertainment. Born in Bridgeport, Connecticut, in 1933, McGuire built her foundation on stage before becoming a familiar face on television.
She made her Broadway debut in the 1955 musical Plain and Fancy, playing Rebecca. That early breakthrough led to appearances in Happy Hunting in 1956 and Oh Captain! in 1958. Along the way, she worked alongside major stage talents including Ethel Merman, Barbara Cook, Bea Arthur and Tony Randall.
