Normalcy:

A commenter recently repeated the claim that President Harding coined the term "normalcy" in his 1920 Presidential campaign. Not so; he may have popularized the term, but it was included in the 1913 Webster's Revised Unabridged Dictionary, and the Oxford English Dictionary attests it back to 1857.

This is further evidence, should you need it, that you should be careful believing linguistic factoids, especially ones about how some word -- whether normalcy, strategery, or lonely -- was supposedly coined by some famous figure.
