One of the hardest working child actresses of the 1950s, Mimi Gibson earned over $100,000 (in 1963 dollars) from appearances in 35 movies and over 100 Television Shows. Her mother took Mimi and her sister to Los Angeles after her father's death when she was a baby. Her mother lived off her acting income. When Mimi turned 18 she found out that all her earnings were gone. At the age of 20 she had become very angry and upset. She skipped getting a college degree and got married to get away from her mother.
She reconciled with her mother a few years later but the experience has bothered her ever since. She is presently active in the Screen Actor's Guild and A Minor Consideration and has pushed for revisions in Coogan's Law that assures actors retain a substantial portion of their income.
