Clement C. Moore (1779–1863), an American scholar and poet, first wrote “The Night Before Christmas” in 1822 to entertain his children. A friend submitted it to a local newspaper, the Troy Sentinel, where it was published on December 23, 1823. Moore’s delightful description of St. Nicholas and his eight flying reindeer has since become the definitive portrait of Santa Claus.Lauren Semmer is an artist, children’s book creator, and designer whose work has been featured everywhere from textile designs and children’s apparel to the New York Times, the Washington Post, and Real Simple magazine.
