Maria von Trapp, a member of the musical family whose escape from Nazi-occupied Austria was the basis for The Sound of Music, has died at the age of 99.

Von Trapp died at her home in Vermont on Tuesday, her brother Johannes von Trapp said.

“She was a lovely woman who was one of the few truly good people,” he said.

“There wasn’t a mean or miserable bone in her body. I think everyone who knew her would agree with that.”

Maria von Trapp was the last surviving member of the seven original Trapp Family Singers made famous in The Sound of Music.

Their story was turned into the film and Broadway musical.

She was the third child and second-oldest daughter of Austrian Naval Captain Georg von Trapp and his first wife, Agathe Whitehead von Trapp.

Their seven children were the basis for the singing family in the 1959 Broadway musical and 1965 film, which won the Oscar for best picture.

Maria von Trapp was portrayed as Louisa in the film and musical.

The Sound of Music was based loosely on a 1949 book by von Trapp’s second wife, also Maria von Trapp, who died in 1987.
