Euphemia Chalmers Millais, Lady Millais (née Gray; 7 May 1828 – 23 December 1897) was a Scottish artists' model and writer who was married to Pre-Raphaelite painter John Everett Millais. She had previously married the art critic John Ruskin, but she left him with the marriage never having been consummated; it was subsequently annulled. This famous Victorian "love triangle" has been dramatised in plays, films, and an opera. Wikipedia
