Arnold Vogler was a German wizard and Quidditch commentator, who might have worked for the German Ministry of Magic. He was a former player of the Heidelberg Harriers, for which he played in an unknown position.
The name "Arnold" comes from a Germanic name meaning "eagle power", derived from the elements arn "eagle" and wald "power". It was brought by the Normans to England, where it replaced the Old English cognate Earnweald.
