Sound Of Music Star Loses Battle To Dementia. Fans Everywhere Mourning Loss Of Iconic Actress.

Charmian Carr, best known for her iconic role as Liesl von Trapp in The Sound of Music, has passed away at the age of 73. According to her spokesperson, Carr passed away from complications of dementia.

Carr was one of the most beloved characters in Rodgers and Hammerstein’s 1965 film, starring alongside Julie Andrews and Christopher Plummer as the eldest von Trapp child. Carr’s performance of the famous song, Sixteen Going On Seventeen, has endeared her to generations of fans.

Carr was always gracious regarding the admiration she received from devoted Sound of Music fans. She repeatedly made appearances at fan events celebrating the film, including performances at the Hollywood Bowl.

Carr wrote a pair of books about her experience playing the iconic teenager, Forever Liesl and Letters To Liesl.

Kym Karath, who played the youngest child Gretl, wrote on Twitter about the deep sadness of Carr’s passing. They played sisters on screen, but have been like sisters throughout their lives.

“It’s always sad when a member of the family passes away and in the case of the ‘family’ of the movie The Sound of Music, it’s especially sad when it is the first of the group to go,” said Ted Chapin, president of the Rodgers and Hammerstein organization.

“Charmian Carr played the oldest von Trapp child, and in some ways she maintained that role in real life guiding, cheering, supporting and generally being there for the rest of her ‘sisters’ and ‘brothers’,” Chapin added.

When Carr retired from acting, she set up a successful interior design business, with Michael Jackson and screenwriter Ernest Lehman among her clientele.

“The Sound of Music lost a beloved member of the family w/ the passing of Charmian Carr,” wrote 20th Century Fox on Twitter. “She will be forever missed.”
