This simple hymn first published in the late 1800s and beloved by children everywhere, is often called "Luther's Cradle Hymn". Some say Luther did not write it, but that some artist imagined he would choose this type of song to sing his own child to sleep. It is now thought to be of American origin. Regardless, it is one of our favourite Christmas songs. The two most-common musical settings are by William J. Kirkpatrick (1895) and James Ramsey Murray (1887). Researchers have not yet confirmed the original lyricist(s).
