American author who wrote the 1823 Christmas poem, "A Visit from St. Nicholas," which later became known as "'Twas the Night Before Christmas." He also had a prominent career as a professor of divinity and literature.

His description of St. Nicholas in his famous poem formed the basis for the modern idea of Santa Claus.

His image of Santa Claus influenced the performance of actor Edmund Gwenn in the classic Christmas film, Miracle on 34th Street.
