who wrote the song rudolph the red-nosed reindeer

The song "Rudolph the Red-Nosed Reindeer" was written by Robert L. May in 1939. May was working as an advertising copywriter at Montgomery Ward, a department store chain, when he came up with the idea for the story. The story was originally published as a children's book, but it was later adapted into a song by Johnny Marks in 1949. The song has since become a classic Christmas carol and has been recorded by many artists over the years.
