I've been studying Mengele for a long time, and nowhere have I ever heard that he took Irma Grese as a lover.  If anything, he was fiercely loyal to his wife, Irene, and she even lived with him at Auschwitz for about a year.  I think a lot of this article is wishful thinking, trying to make another cruel SS guard into some romantic heroine.  Rebecca, Myrtle Beach SC 10/07/06
