Betty Grable was the youngest of three children. Unlike other profiled here, she entered into show business at her mother's prodding and not out of necessity of the income. She began working in a chorus line at age 13. Her age was not easily discerned because the chorus line performed in black face. (Yikes!) Grable eventually became a contract player at 20th Century Fox and went on to be one of their top stars in the 1940s.
In 1943, Betty posed for a pin up photo for the troops fighting in World War II. The iconic picture is recognizable even to those born well after WWII and those who might not know who Grable is.
Grable would appear in 80 movies and on television in her career. She was nicknamed "The Girl With The Million Dollar Legs" and "The Pin Up Girl". Sadly, Grable passed away in 1973 of lung cancer.
