At her peak, during the 50s, Betty was the highest paid pin-up model in the world. A shrewd businesswoman, she was the first model to successfully demand residuals every time her photo was used and owned the rights to many of the negatives of her pictures. With her husband, bodybuilder Joe Weider, she founded Shape magazine, a health and fitness magazine for women. At the age of 74, she still looks great and continues to write two monthly columns on women's health.
I just love this picture of her getting her nerd on.
