In 1939, May wrote a Christmas-themed story-poem to help bring holiday traffic into his store. Using a similar rhyme pattern to Moore's "'Twas the Night Before Christmas," May told the story of Rudolph, a young reindeer who was teased by the other deer because of his large, glowing, red nose.
But, When Christmas Eve turned foggy and Santa worried that he wouldn't be able to deliver gifts that night, the former outcast saved Christmas by leading the sleigh by the light of his red nose. Rudolph's message—that given the opportunity, a liability can be turned into an asset—proved popular. Montgomery Ward sold almost two and a half million copies of the story in 1939.
When it was reissued in 1946, the book sold over three and half million copies. Several years later, one of May's friends, Johnny Marks, wrote a short song based on Rudolph's story (1949). It was recorded by Gene Autry and sold over two million copies. Since then, the story has been translated into 25 languages and been made into a television movie, narrated by Burl Ives, which has charmed audiences every year since 1964.
