Doreen Tracey, one of the Mickey Mouse Club;s original Mouseketeers, died from pneumonia on Wednesday, January 10, 2018 at age 74, at Los Robles Hospital in Thousand Oaks, CA, a result of complications from a two-year battle with cancer. Tracey, known for her a vivacious personality and all-around performance skills, appeared on the show throughout its four-year run (1955-1959) on ABC. The original Mickey Mouse Club lived on in syndication for decades thereafter entertaining generations of children around the world.

Tracey was born in London, England, on April 3, 1943, to a theatrical family. Her parents, Bessie Hay and Sid Tracey, had a vaudeville dance act known as Tracey and Hay. When Doreen was four, her family returned to the United States where her father opened a dance studio in Hollywood. It was there that Tracey learned to sing and dance and at age twelve auditioned for the Mickey Mouse Club. During her tenure as a Mouseketeer, Tracey was also cast in Walt Disney Production's 1956 feature film, Westward Ho the Wagons! starring Fess
Parker. Additionally, she went on to appear on the Mickey Mouse Club's Annette serial, and toured Australia with the Mouseketeers.

Following the Mickey Mouse Club years, in the 1960s Tracey continued her show business career guest-starring on several episodic television programs as well as touring American military bases in South Vietnam and Thailand with her own act. After returning to the US, she shifted gears to working behind-the- scenes and held positions that included publicist to musician and composer Frank Zappa as well as enjoying a multi-decade career in administration at Warner Bros. And while Tracey;s career took many different paths, she always remained close to her Disney roots maintaining long-time friendships with her fellow Mouseketeers.

In the 80s, 90s, and 2000s she co-starred with them in several Mickey Mouse Club reunion shows at Disneyland and at Disney conventions, last celebrating the show's 60th Anniversary in 2015. "Our Dodo, as we lovingly nicknamed her, always had a smile on her face," said fellow Mouseketeer Tommy Cole. "She never failed to make us all feel good and we will miss her."

Divorced, Tracey is survived by her son, Bradley, and two grandchildren, Gavin, age 9, and Autumn, 12. Bradley said of his mother, "She was very brave, very
independent, and very loved by her family."
