British Westinghouse

British Westinghouse Electrical and Manufacturing Company was a subsidiary of the Pittsburgh, USA based Westinghouse Electric and Manufacturing Company. British Westinghouse would become a subsidiary of Metropolitan-Vickers in 1919; and after Metropolitan-Vickers merged with British Thomson-Houston in 1929, it became part of Associated Electrical Industries (AEI) in 1959. Further consolidation saw AEI taken over by GEC in 1967.


George Westinghouse established British Westinghouse in 1899 with capital from his own company and a smaller share from UK investors. The company commenced the construction of its first factory in Trafford Park, Manchester the same year. Manufacturing began in 1902, the same year as the rival British Thomson-Houston (BTH). BTH was majority owned by General Electric and the competition between BTH and British Westinghouse mirrored that of the parent companies, GE and Westinghouse in America.
