The story
The company was founded by the Yorkshire-born engineer Guy Fountain (1898-1977) at a garage in Tulsemere Road, Dulwich in London as the Tulsemere Manufacturing Company. It originally made battery chargers for wireless radio sets. The company name was changed to Tannoy in 1928 and a small factory was opened in Dalton Road, West Norwood, later moving to Canterbury Grove. Tannoy Square SE27 commemorates the site today.
During World War II Tannoy public address systems were supplied to the armed forces, and a Tannoy PA system was used at Buckingham Palace in 1945 to announce the end of hostilities. Tannoy speakers were also supplied to factories around Britain to relay the BBC's motivational radio series Music While You Work, and to Butlins and Pontins holiday camps following the war - where they were famously used to waken guests with the words "Good morning, campers!". The Tannoy factory moved from Canterbury Grove to Coatbridge, Scotland in the 1970s.
In 2002, Tannoy was acquired by TC Group, and TC Group was subsequently acquired by Music Group in 2015. Following the Music Group acquisition, it was suggested that the Coatbridge facility would be closed and all related activities would be relocated to Manchester, England. In 2016, however, Music Group confirmed that Tannoy loudspeaker manufacturing would continue in Scotland, with a brand new manufacturing facility planned.
