After Rupert D'Oyly Carte died in 1948 his daughter, Bridget D'Oyly Carte, succeeded to the D'Oyly Carte Opera Company and became a director and later president of the Savoy Hotel group, which controlled the theatre. Management of the theatre was assumed in 1948 by Sir Hugh Wontner, chairman of the Savoy hotel group. The theatre was designated a Grade II* listed building in 1973. The D'Oyly Carte Opera Company closed in 1982, and Dame Bridget died childless in 1985, bringing the family line to an end. Wontner continued as chairman of the theatre until his death in 1992.
