Well, I'm glad you asked. The poem was written by Clement Clarke Moore, a professor of theology at Columbia University in New York City. Moore wrote the poem as a Christmas gift for his children in 1822, and it quickly became a popular holiday tradition. It's a classic tale of Santa Claus and his reindeer flying through the night to deliver presents to children everywhere. Moore's poem has been translated into many languages and has been performed as a Christmas play for over 200 years.
