Dickens did not quite “invent” Christmas, as it is sometimes claimed, but, ever since A Christmas Carol was published in 1843, Scrooge’s Yuletide nightmares and joyful Christmas morning have become as much a part of the popular idea of the season as Christmas trees and endless, maddening renditions of “Jingle Bells.” A little searching yields about 1,700 different editions of A Christmas Carol for sale, and theatrical performances are an annual tradition.
