Peter Christian Frederik Faber (7 October 1810, Copenhagen – 25 April 1877) was a Danish telegraphy pioneer. In Denmark, he is remembered first and foremost for his songwriting. Faber was also an amateur photographer and is credited with the oldest photograph on record in Denmark. ==Telegraphy== After graduating in technology in 1840, he became an inspector at the Polyteknisk Læreanstalt (College of Advanced Technology) where he carefully followed the development of electromagnetic telegraphy. Together with Hans Christian Ørsted he wrote a report on the possibility of laying telegraph lines in Denmark. When a line successfully connected Helsingør and Hamburg, he became the director responsible. Faber quickly replaced the underground cables with overhead wires, extending the telegraph network from 530 km to 2,800 km with 200 relay stations and over 300 employees.〔(Peter Faber.
