Houdini
Houdini may be a variant of Yehudi, which means “leader”.
The name Houdini also appears in the French variants Houdin, Hodin, Oudin, Odin.
Harry Houdini’s name was officially copied from Jean Eugène Robert-Houdin, who in turn took the name from his wife Josèphe Cecile Houdin.
Harry Houdini was also officially a Jew.
In Aramaic, הוד hwd means leader. The N is a common grammar suffix for verbs & nouns. In regular Aramaic language, there are many N-suffixed variants of הוד hwd, which look & sound a lot like the names Houdin and Houdini.
Aramaic hd-n = leader, leadership
The names Houdin & Houdini may thus mean Jew in the sense of leader. Since Houdin & Houdini were illusionists, for them the name may also mean “mis-leading the audience”.
