Actress Katherine Helmond died on Friday, March 1, 2019, in her Los Angeles home. She was 89 years old at the time of her death. The cause of death was reported to have been complications from Alzheimer’s disease.

“She was the love of my life. We spent 57 beautiful, wonderful, loving years together, which I will treasure forever,” her husband, David Christian, said. “I’ve been with Katherine since I was 19 years old. The night she died, I saw that the moon was exactly half-full, just as I am now… half of what I’ve been my entire adult life.”

Helmond was known for stealing the show when she was on screen in “Who’s the Boss?” and “Soap.” She performed as an actress for nearly five decades and was nominated for multiple Emmy Awards. She also won two Golden Globes in 1981 and 1989. The Globes were won for her work on “Soap,” where she played lovably naive Jessica Tate, and “Who’s the Boss,” where Helmond portrayed the feisty mother Mona Robinson.

In addition to her well-known television roles, Helmond also appeared in films and on stage. She earned a Tony Award in 1973 for her performance in Eugene O’Neill’s “The Great God Brown.” She also appeared in the films “Time Bandits,” “Brazil,” “Fear and Loathing in Las Vegas” and had a voice role for the animated Pixar film “Cars.”

Helmond’s fellow actors and celebrities have spoken fondly of her following her death. Tony Danza called the actress a “national treasure” and said “no words can measure my love.” Similarly, Alyssa Milano stated that Helmond was “beautiful, kind, funny, gracious, compassionate” and “an instrumental part of my life.” Joe Mantegna also said that Helmond was “a joy and an inspiration in my career and life.”

There will be a memorial for Helmond’s family and friends, but no details are available yet. There is no doubt, however, that Helmond will be missed by those who knew her on screen as well as those who knew her best.
