Danica McKellar

Danica McKellar is one of the best examples of an actress who people know more about by her character’s name than her name. She famously played Winnie Cooper, longtime friend, and girlfriend of Fred Savage’s Kevin Arnold on The Wonder Years.

After the show ended, she went on to get a B.S. in mathematics from UCLA and write several books on improving math education, as well as appearing before a Congressional subcommittee in 2000 to promote ways to increase the number of women in math-related fields. She is also still acting and provided the voice of a superhero on the animated show Young Justice.
