Webster's New World Dictionary of the American Language College Edition -- by The World Publishing Company of New York 1966.

One dictionary (hint: just because it says Webster on the cover doesn't make it good. Webster is not trademarked and can go on any dictionary at all). I've checked several more online sources and none of them have this meaning. Not one. I've checked two thesauri and neither have this in their list of synonyms for the devil - although the list is pretty intersting. I found "Old Nick", "Old Scratch" and similar names, but nothing to do with 'Harry'.

The Webster's Dictionary above is nearly 1800 pages, was a required reference dictionary for my university studies and is in the libraries all around here. Not everything appears online. Things that are written down on paper cannot be erased like things written in electronic digits. "Harry" was around long before the computer was invented. All you have found so far is everywhere that the "Harry" is not. I'm simply telling you and others where "Harry" is -- the Webster's Dictionary .
