The woman who made Liesl Von Trapp a household name has passed away at the age of 73.
The Sound of Music star, Charmian Carr, died from complications arising from a rare form of dementia, according to a statement published on her website.
"Carr was best known for acting, but much of her life revolved around her family and her interior design business," the statement read.
"After acting in The Sound of Music, she married and then decided to leave the movie business and raise her two children, Jennifer and Emily. It was a decision she never regretted."
Charmian's family paid special tribute to her friendship with The Sound of Music cast:
"Through the years the actors who played the children in the movie all kept in touch and communicated often. Carr considered them her second family."
Charmian played the role of the eldest Von Trapp daughter, Liesl, in the 1965 film starring Julie Andrews and Christopher Plummer.
Many will remember her performance of the song, Sixteen Going on Seventeen.
Charmian had two daughters and four grandchildren.
