Sue Mengers was born on 2 September 1932 in Hamburg, Germany. She was married to Jean-Claude Tramont. She died on 15 October 2011 in Beverly Hills, California, USA.
Dyan Cannon's character "Christine" in The Last of Sheila (1973) was based on Mengers, as was Shelley Winters's character "Eva Brown" in S.O.B. (1981), which starred Julie Andrews and was directed by Andrews's husband Blake Edwards. In response to this latter satirical portrayal of her, Mengers responded to the Edwardses with this: "An Alp should fall on their house.".
