Menzies-Urich’s son, Ryan Urich, told Variety that his mother passed away late Sunday after battling brain cancer.

“She was an actress, a ballerina and loved living her life to the fullest. She was not in any pain but, nearly four weeks after her diagnosis of terminal brain cancer, she had enough and took her last breath on this earth at 7: 22 p.m.,” Urich said.

Ted Chapin, the president of the Rodgers and Hammerstein Organization, said in a statement: “Heather was part of ‘the family.’ There is really no other way to describe the members of the cast of the movie of ‘The Sound of Music. Heather was a cheerful and positive member of the group, always hoping for the next gathering. We are all lucky to have known her, and she will happily live on in that beautiful movie. We will miss her,” BBC reported.
