Marie Doro was an American stage and film actress of the early silent film era.
Marie Doro was born as Marie Katherine Steward in Duncannon, Pennsylvania and began her career as a theater actress before progressing to motion pictures in 1915, under contract with film producer Adolph Zukor.
She was briefly married to the vaudeville and silent screen actor Elliott Dexter; the marriage soon ended in divorce. The marriage produced no children and Doro never remarried. Her name was linked over the years to much older William Gillette, of Sherlock Holmes fame, who was probably infatuated with her.
Doro's film debut for Zukor's Famous Players studio was the starring role in the now lost short film The Morals of Marcus in 1915.
