Her family announced that she died of complications from a rare form of dementia.

Charmian Carr, known for her role as Liesl Von Trapp in The Sound of Music, has died. She was 73.

Carr's family announced she died Saturday in Woodland Hills of complications from a rare form of dementia. 

Carr was born on Dec. 27, 1942, in Chicago. She was 21 when she sang the popular "Sixteen Going on Seventeen" as the oldest Von Trapp sister in the Academy Award-winning Sound of Music (1965), starring Julie Andrews and Christopher Plummer. 

Carr starred in only one other film, appearing opposite Anthony Perkins in Evening Primrose (1966).

After she left the movie business, Carr started a design company called Charmian Carr Design, which attracted Michael Jackson as a client. 

Carr co-authored two books: Forever Liesl (2000), which chronicled her experience filming Sound of Music, and Letters to Liesl (2001), which was inspired by the thousands of pieces of fan mail she received over the years. 

Carr is survived by her siblings Sharon, Darleen, Michael and Brian; daughters Jennifer and Emily; niece Julie; and grandchildren Emma, Derek, William and Tucker.
