Rest in peace, Charmian Carr.
The actress — who famously played eldest Von Trapp daughter, Liesl, in 1965's The Sound of Music — sadly died of complications from a rare form of dementia on Saturday, Sept. 17, according to a statement on her official website. She was 73-years-old.

In addition to starring in The Sound of Music — during the film she famously sang "I Am Sixteen Going on Seventeen" — Charmian appeared in the Stephen Sondheim TV musical Evening Primrose in 1966.
In the late 1960s, Charmian retired from acting to raise her two daughters and establish her own interior design business. The star is survived by her four siblings, two children and four grandchildren. Our thoughts are with Charmian's family and friends during this difficult time.
