Peter Christian Frederik Faber (7 October 1810 in Copenhagen – 25 April 1877) was a Danish telegraphy pioneer and song writer.
Together with Hans Christian Ørsted he wrote a report on the possibility of laying telegraph lines in Denmark.
They include Højt fra træets grønne top which is always sung around the family Christmas tree, and Dengang jeg drog af sted, written to celebrate the Danish victory at the 1848 Battle of Bov.
A careful analysis of the photograph is claimed to show that it dates back to July 1840.
The exposure time of about 15 minutes in sunlight explains why the only figure to be seen is a man sleeping at the foot of the Pillar of Shame towards the left of the picture.
