Lucia Chamberlain (1882–1978) was an American novelist. Her 1909 book was the basis of the 1916 film The Other Side of the Door, and her 1917 short story "The Underside" formed the basis of the 1920 film Blackmail. The 1916 film The Wedding Guest is also based on her writing. This photograph of Chamberlain was taken around 1908 by the American portrait photographer Zaida Ben-Yusuf, and is now in the collection of the National Portrait Gallery in Washington, D.C.
