Gloria Henry – Age 95
It’s quite hard to forget stars who became part of an iconic TV sitcom just like the cast of Dennis the Menace. One of the unforgettable stars of the show is Gloria Henry, the actress behind the character of Alice. She went to the Worcester Art Museum School, although it’s quite unsure if she was able to earn her degree. Unfortunately, her career started declining after the show and she didn’t have many roles after it. She last appeared on the show Parks and Recreation back in 2012. After her last guest stint, she chose to fully retire from acting.
