3. Lucille Ricksen (Age 14)

Lucille Ricksen started as a baby model and became a child actress in the silent film era. She starred in serials like The Adventures of Edgar Pomeroy and toured the country as a young star.
She died at 14 from tuberculosis, exacerbated by overwork and physical collapse while filming. Her case became an early example of the dangers of exploiting child performers in Hollywood.
