How Santa’s ninth reindeer made his on-screen debut.
By Maria Popova
In 1939, Robert L. May conceived of Rudolph the Red-Nosed Reindeer in a poem, published in a booklet by iconic department store Montgomery Ward. But “Santa’s 9th Reindeer” didn’t become etched into the nation’s collective imagination until May’s brother-in-law, songwriter Johnny Marks, adapted Rudolph into a song in 1949. (What makes the story all the more curious and poetic is that Marks was Jewish, yet he created some of the most popular Christmas songs we know today.)
