Elinor Glyn ( Sutherland; 17 October 1864 – 23 September 1943) was a British novelist and scriptwriter who specialised in romantic fiction, which was considered scandalous for its time, although her works are relatively tame by modern standards. She popularized the concept of the "it girl", and had tremendous influence on early 20th-century popular culture and, possibly, on the careers of notable Hollywood stars such as Rudolph Valentino, Gloria Swanson and, especially, Clara Bow.
