De'vo Vom Schattenreich is the stage name of David Beyer, a (former?) US service member and magician who has made a killing selling instructional dvd's through his superhandz and handlordz web sites.
He created a whole back story for his pseudonym that involved ancient card juggling rituals passed down through a secret society that met in an abandoned castle. It was all a bit over the top, but the kids ate it up. I'm not sure he still sticks to that story anymore.
He founded Superhandz and was one of the driving forces behind XCM. In fact, he owns the trademark for the term Xtreme Card Manipulation.
David R. Beyer from Aurora, Colorado.
Tech. Sgt. Dave Beyer. with 460th Services Division (Buckley's Air Force Base in Aurora Colorado). He was eventually stationed in Germany around the same time De'Vo went there. His wife had domains registered under her name there until someone made the details public. At which point they were switched over to anonymous domain registrars. He likes his anonymity.
