TELEGRAPHY MENU


This site is mainly about telephones but included here is a small selection of BPO Telegraphy items, including a large section on the Central Telegraph Office.  Telegraphy was used to transmit telegrams on a very large scale before the introduction of the telephone and continued into the eighties.  It was the fore runner of the digital age and was connected worldwide!  These pages are more about the general operation of the telegraph system and the apparatus involved, rather than an in depth technical description of the working principles.
