You probably know her as the lady who wrapped a cat. Or maybe you know her as the squeaky, "boop-oop-a-doop" voice of a 1930s icon. Mae Questel was a force of nature in Hollywood for nearly seventy years, but her final chapter was a lot quieter than the characters she brought to life.
She died at 89.
It wasn't a sudden tragedy or a Hollywood scandal. Honestly, it was the kind of slow fade that hits many families, though that doesn't make it any less heavy for the people who grew up with her voice in their ears. If you’ve ever wondered about the Mae Questel cause of death, the reality is tied to a long battle with Alzheimer’s disease.
The Reality of the Mae Questel Cause of Death
Mae Questel passed away on January 4, 1998. She was in her Manhattan apartment when it happened. For a woman who spent her life making people laugh and "boop," her later years were defined by the complications of Alzheimer's.
It’s a brutal disease. It robs you of the very thing Mae used to build her career: her wit and her memory for timing. By the time she passed, she had been out of the spotlight for a few years, living a much more private life in New York than she ever did during the vaudeville days.

Most sources, including her official records, confirm that she died from complications related to the disease. She was 89 years old, just shy of hitting that 90-year milestone. She’s buried now in New Montefiore Cemetery in West Babylon, but her voice? That’s still everywhere.
A Career That Wouldn't Quit
To understand why people still care about how she died, you have to look at what she did. Mae didn't just play characters; she became them.
- Betty Boop: She wasn't the first voice, but she was the one everyone remembers. She won a talent contest at 17 by imitating Helen Kane, and Max Fleischer basically handed her the keys to the kingdom.
- Olive Oyl: She voiced Popeye's girlfriend for over 20 years. Think about that. Most actors today can't stay on a show for three seasons without a reboot.
- Aunt Bethany: This is the big one for the younger crowd. In National Lampoon’s Christmas Vacation, she plays the senile aunt. It was her final film role.
It’s kind of poetic, in a sad way. In that movie, her character is clearly struggling with memory—reciting the Pledge of Allegiance instead of saying grace. Real life ended up mirroring that bit of fiction as her own health declined in the years following the film's 1989 release.
Why Her Passing Felt Like the End of an Era
When Mae died in early 1998, it wasn't just a celebrity death. It was the loss of a link to the "Golden Age" of animation. There was a specific texture to her voice that you just don't hear anymore.

She lived through the transition from silent films to talkies. She saw the rise of television. She even did the "Aunt Bluebell" commercials for Scott Towels. Basically, if you lived in America between 1930 and 1990, you heard Mae Questel. You just might not have known it was her.
The Complications Nobody Talks About
Alzheimer’s isn't just "forgetting things." In the elderly, it often leads to secondary issues like pneumonia or a general "failure to thrive" where the body just forgets how to keep going.
In Mae’s case, she had been retired from the screen since about 1989. While she did a few voice reprisal bits—like playing Betty Boop one last time in Who Framed Roger Rabbit—her health was the primary reason she stopped working. She had a supportive husband, Jack Shelby, who passed away just two years before she did. Some say losing a long-term partner can accelerate a decline in someone already struggling with cognitive health. It's a common pattern.
How to Remember Mae Today
If you’re looking for a way to honor her legacy, don't focus on the hospital room in Manhattan. Focus on the work.

- Watch the "Pledge" scene. Go back and watch Christmas Vacation. Knowing she was a legendary voice artist makes her performance as the ditzy Aunt Bethany even more impressive.
- Listen to the range. Find old Popeye shorts. She actually voiced Popeye himself for a few episodes when the regular actor, Jack Mercer, was away in the military. She had that much range.
- Appreciate the history. She was a Russian-Polish American Jewish girl from the Bronx who became the face (and voice) of a global icon.
The Mae Questel cause of death might have been Alzheimer's, but that's not the story. The story is the 150+ cartoons, the Broadway shows, and the fact that 100 years from now, people will still know what "Boop-oop-a-doop" means.
If you are dealing with a family member facing similar health struggles, looking into the resources provided by the Alzheimer's Association can offer some actual, practical guidance on navigating those final stages. Mae’s life shows that even a long, vibrant career ends eventually, but the impact you leave behind is what actually sticks.
Take a moment to look up her live-action appearance in the 1931 short Musical Justice. Seeing the real face behind Betty Boop is a trip—she looked exactly like the character. It’s the best way to remember her: young, vibrant, and full of that New York energy.
