Good job, Scott, that is correct!
I first tried to no avail to find a depiction of the first Xmas tree Franklin Pierce set up in the White House in 1856. I just found this contemporary illustration by Winslow Homer, titled "The Christmas-Tree", which appeared in Harper's Weekly on Dec. 25, 1858:

In 1961 First Lady Jacqueline Kennedy was the first to add a theme for the tree: The Nutcracker Suite. Forgive me, I just can't let you off without the original - although the following is from a "Nutcracker" production by one of the greatest choreographers of our days, the late Maurice Bejart, the "Dance of the Sugar Plum Fairy" remained Marius Petipa's orignal 1892 choreography: http://m.youtube.com/watch?v=Nuk5Sknh1rY
