Telephone Fog Horn

In 1844, Captain J.N. Taylor of the Royal Navy first demonstrated the fog horn. At the time, it was called a telephone - to mean far-signalling, thus an instrument like a fog-horn, used on ships, railway trains, etc., for signalling by loud sounds or notes. The 19 Jul 1844 Times (London) reported, “Yesterday week was a levée day at the Admiralty, and amongst the numerous models..was Captain J. N. Tayler's telephone instrument... The chief object of this powerful wind instrument is to convey signals during foggy weather. Also the Illustrated London News on 24 Aug. 1844 referred to “The Telephone; a Telegraphic Alarum. Amongst the many valuable inventions..that of the ‘Telephone, or Marine Alarum and Signal Trumpet,’ by Captain J. N. Taylor.”
