Ebenezer Scrooge is the main character in Charles Dickens' 1843 novella A Christmas Carol. His name has come into the English language as a byword for miserliness and misanthropy, traits displayed by Scrooge in the exaggerated manner for which Dickens is well-known. The story of his transformation by the three Ghosts of Christmas (Past, Present and Future) is a defining tale of the Christmas holiday.
Scrooge's phrase, "Bah, humbug!" has been used to express disgust with Christmas traditions in modern times. (from Wikipedia)
