Gylnn’s passing was confirmed by her daughter, actress Mary Stuart Masterson (Sid Is Dead), who announced on Instagram that her mother died on Thursday, July 14, after battles with dementia and cancer. Masterson revealed that she was with her mother when she passed away.
“I will always be grateful for those last moments, no matter how hard,” Masterson wrote. “Death is like birth in the oddest way. From my first breath to her last. This thread is as fragile as it is strong.”
“She was the most graceful clumsy person you would ever meet,” she continued. “Strong, smart, silly, intuitive, kind, generous, passionate and a deep listener. She was devoted to my father and to the enormous circle of students and collaborators who were considered her chosen family.”
Masterson shared a selection of photos alongside her message, including a picture from Glynn’s 80th birthday party.
“The last photo is from her 80th birthday party, before the worst of dementia and cancer took their toll,” Masterson said. “She never lost her sense of joy or wonder.”
Born on February 19, 1940, in Cleveland, Ohio, Glynn made her Broadway debut in 1979’s The Best Little Whorehouse in Texas, adapted by Glynn’s husband, Peter Masterson. Glynn earned a Tony Award for Outstanding Featured Actress in a Musical for her portrayal of Mona Stangley.
