August Kopff
666 Desdemona is a stony asteroid from the middle region of the asteroid belt, approximately 29 kilometers in diameter. It was discovered on 23 July 1908, by German astronomer August Kopff at Heidelberg Observatory in southern Germany, and named after Desdemona, character in Shakespeare's "The Tragedy of Othello, the Moor of Venice". The name may have been inspired by the asteroid's provisional designation "1908 DM".
