Clemence Dane was the pen-name of the novelist, dramatist, painter and sculptor Winifred Ashton who was a close friend of Noel Coward from the mid 1920s. She studied painting under Henry Tonks at the Slade School but never sold a picture in her life-time preferring to give them to her friends.

An oil portrait and bronze bust of Sir Noel Coward are in the collection of the National Portrait Gallery and Clemence's portraits are considered to be the truest likenesses of Coward
