Karen Pendleton, one of the original Mouseketeers, has passed away at the age of 73.
She was one of only nine kids who appeared on The Mickey Mouse Club during its entire original run.
According to The Hollywood Reporter, Pendleton died from a heart attack on Sunday in Fresno, California.
Among the youngest of the kids on the show, Pendleton was known for her shoulder-length blond curls and for being paired with fellow Mouseketeer Cubby O’Brien in the show’s sweet closing number, Alma Mater (“Now it’s time to say goodbye to all our company …”).
Pendleton worked on the Disney series throughout its four-year run (1955-59) on ABC, then entertained generations of children around the world for decades after it played in syndication. She was one of only nine kids that appeared on the program during its entire original airing.
Pendleton also co-starred in many Mickey Mouse Club reunion shows and parades at Disneyland and at fan shows and conventions.
