Tycho Brahe lost his nose in a duel with his cousin, caused by a disagreement over an equation that got "a little heated". (COMIC: Herald of Madness) The nose was replaced by a facsimile. After Brahe's death, his body was buried in a cemetery in Prague. In the 24th century, his body was unearthed by the Third Doctor and Sergeant Kandula during the search for the Tipping Device.
