Otto is a masculine German given name. It originates as an Old High German short form (variants Audo, Odo, Udo) of Germanic names beginning in aud-, an element meaning "wealth, prosperity". The name is recorded from the 7th century (Odo, son of Uro, courtier of Sigebert III). It was the name of three 10th-century German kings, the first of whom was Otto I the Great, the first Holy Roman Emperor, founder of the Ottonian dynasty. The Gothic form of the prefix was auda- (as in e.g. Audaþius), the Anglo-Saxon form was ead- (as in e.g. Eadmund), the Old Norse form was auð-.
