Dawn Langley Pepita Simmons (1922 – September 18, 2000) was a successful English author and biographer. As a young adult, she became close to British actress Dame Margaret Rutherford, who became her adoptive mother. Later, Simmons wrote Rutherford’s biography. After gender reassignment surgery in 1968, Simmons married her previous chauffeur in the first legal “interracial” marriage in South Carolina. The couple’s marriage was also a statement in response to the assassination of Martin Luther King a few months earlier.
