On a cold Christmas Eve in the year 1818, a young priest named Joseph Mohr quickly walked from his home in the small town in Oberndorf, Austria to the neighboring village of Amsdorf. He was carrying a piece of paper – a poem he had written two years earlier.

He made his way to the schoolhouse, walked up the stairs and knocked on the door of the second floor apartment. He was greeted by his friend, Franz Gruber, the schoolmaster in Amsdorf and also the church organist.
