On a snowy evening in December 1823, a poem titled A Visit from St. Nicholas—better known as The Night Before Christmas—made its debut in the Troy Sentinel. The enchanting story of Santa Claus, a jolly figure flying in a sleigh pulled by reindeer, transformed how Christmas was celebrated, turning it into the family-focused holiday we cherish today. But who truly wrote it? While Manhattan professor Clement Clarke Moore claimed authorship in 1844, others argue it was Henry Livingston Jr., a poet from New York’s Hudson Valley. This episode unravels the fascinating origins of the poem that gave us Santa’s iconic image, the reindeer’s thunderous names, and a heartwarming farewell: “Happy Christmas to all, and to all a good night.”
