Lore & Background
Thorn Electrical Industries traces its origins to Jules Thorn, who migrated from Austria in 1923 and initially worked as a travelling salesman. After his employer went bankrupt in 1926, Thorn set up the Electric Lamp Service Company, dealing in electrical and radio goods. The company was incorporated on 29 March 1928. In 1932, Thorn acquired the Atlas Lamp Works company and began manufacturing light bulbs at a factory in Edmonton. In 1936, Thorn started distributing radios for the Ferguson Radio Corporation, which it acquired in 1946. That same year, the company changed its name to Thorn Electrical Industries Limited and became a public limited company.
During the 1950s and 1960s, Thorn expanded aggressively. It struck deals with Bendix Aviation Corporation and EMI Group to produce products on their behalf, and acquired Philco's British interests. In 1961, Ultra Electronics's consumer electronics interests were integrated, and in 1964 Thorn merged its lighting interests with those of Associated Electrical Industries to form British Lighting Industries. In 1968, Thorn acquired Radio Rentals for £180 million and completed a hostile takeover of Kenwood Manufacturing. By that year, the company operated over fifty factories in the UK and eight overseas. In 1969, Thorn merged with EMI Group to form Thorn EMI.
Reader's Guide
Thorn Electrical Industries was a significant force in British manufacturing for much of the 20th century. Its acquisition of Ferguson in 1946 gave it a strong position in radio and later television production, and its brands—Ferguson, Ultra, HMV, Marconiphone—became household names. The company's lighting division, under the Atlas, Mazda, and Ekco brands, held the largest share of the UK lighting market by 1968 and was the largest exporter of lighting equipment from the UK. Thorn's domestic appliances division, with brands such as Tricity, Main, and Moffat, also commanded substantial market share in cookers and other appliances.
The merger with EMI in 1969 created Thorn EMI, a conglomerate that operated for nearly 30 years. After being de-merged in 1996, Thorn regained its individual listing briefly before being acquired by Nomura Group in 1998. It was later transferred to Terra Firma Capital Partners, and parts of the company were sold off in 2007. The company's legacy includes its role in popularizing television rental through Radio Rentals and DER, and its extensive manufacturing base across the UK and overseas.
