Who invented the Christmas card?

Sir Henry Cole was a prominent innovator in the 1800s. He modernized the British postal system, managed construction of the Albert Hall, arranged for the Great Exhibition in 1851, and oversaw the inauguration of the Victoria and Albert Museum. Most of all, Cole sought to "beautify life," and in his spare time he ran an art shop on Bond Street, specializing in decorative objects for the home. In the summer of 1843, he commissioned John Calcott Horsley to design an impressive card for that year's Christmas.
