Who wrote Jolly Old St Nicholas?

If I am not mistaken the radio singer Ray Heatherton, the so-called Merry Mailman, helped to popularize this song, ( a good side line, as well Christmas makes bigs bucks for the post office!) I had this record as a kid. For some odd reason it isn"t widely played, I have not heard it on the Yule stations for a couple of seasons. It is a good family type song, nothing offensive.
