Betty Grable (1916-1973) was an American actress, singer, and dancer who was one of the most popular movie stars of the 1940s. She was known for her pin-up girl looks, as well as her musical talents and comedic timing.

Grable began her career as a chorus girl in Broadway musicals before making her film debut in the 1930s. She quickly became a star at 20th Century Fox, where she appeared in a series of successful musicals, including "Down Argentine Way" (1940), "Moon Over Miami" (1941), and "Sweet Rosie O'Grady" (1943). She was also known for her famous pin-up photos, which were widely circulated during World War II and made her one of the highest-paid actresses in Hollywood.

Grable's career continued into the 1950s, although her popularity began to decline as musical films became less popular. She made her final film appearance in "How to Be Very, Very Popular" (1955) before retiring from the screen to focus on her family life.
