Clement Clarke Moore (July 15, 1779 – July 10, 1863) was an American Professor of Oriental and Greek Literature, as well as Divinity and Biblical Learning, at the General Theological Seminary of the Protestant Episcopal Church. He is the author of the yuletide poem "A Visit from St. Nicholas", which later became famous as "'Twas the Night Before Christmas".
This poem seems to be a 'moral' version of "The Night Before Christmas".
