Doppelgängers
Sumana: it's originally Doppelgänger. My old New Cassell's claims it comes from parts meaning "double-goer".
You get similar transliteration problems in names like Schroeder, Schaefer, and Schoen. (Did you know that Pat Schroeder and Bruce Lehman were both there in the room when Jack Valenti gave his "Boston strangler" testimony?)
