Sir Felix Pole was born and raised in Wiltshire. In 1891, at the age of 14, he joined the the Great Western Railway as a telegraph lad clerk. After two years he was promoted, moving to the company's headquarters at Paddington in London, serving in the offices of the telegraph superintendent, chief engineer, and general manager. Pole edited the GWR's staff magazine, Great Western Magazine, and distinguished himself through his involvement with the conciliation boards. A promotion followed, and Pole was made head of the staff and labour department in the general manager's office in 1912. In June 1913 was appointed chief clerk, a position he held throughout the period of the First World War as his poor eyesight meant he was rejected by the armed forces. By March 1919 Pole was assistant to the general manager, Frank Potter, and, after Potter's death that August Pole became assistant general manager to Charles Aldington. Aldington was by this time in poor health, which created opportunities for Pole. Pole succeeded Adlington in June 1921, when the latter was forced to retire for health reasons. Under the Railways Act of 1921, GWR was greatly expanded to incorporate thirty-three formerly separate companies. A key part of Pole's mission was to successfully integrate these disparate parts. Pole was also tasked with restoring financial stability after wartime government control. He was credited with fostering good relations within the company, with customers and with the general public. Pole used his many addresses to chambers of commerce, rotary clubs, and civic functions to these ends. Pole was knighted in 1924. In July 1929, Pole left the GWR to become chairman of Associated Electrical Industries Ltd., although he remained a consultant to his old employer. AEI manufactured electric goods. It had been recently formed out of a group of companies including British Thomson-Houston, Ferguson Pailin, Edison Swan, Metropolitan-Vickers, and others. Once again, Pole's task was one of integration and creating a sense of identity. Alongside his role at AEI Ltd, Pole also sat as Chairman of the Rural Housing Committee from 1936 until 1945, advising the British government. The loss of his sight promoted Pole to resign as Chairman of AEI in 1945, but he remained a company director until 1955. He died in January, 1956.

Associated Electrical Industries (AEI) was formed in 1928 as a financial holding company for a number of leading electrical manufacturing and trading companies in the United Kingdom. The two major constituent companies were British Thomson-Houston (BTH) based at Rugby, (Mill Road Works) and Metropolitan-Vickers Electrical Company Ltd (Metrovicks) situated at Trafford Park, Manchester. However, fierce rivalry existed between the Metrovick and BTH brands resulting in internal competition and duplicated management. This was highlighted during the Second World War in 1939, when Metrovicks and BTH became the first two firms in the world to construct jet engines (independently from each other). Following the Second World War, in 1954, AEI expanded to consist of BTH, Metrovicks, Edison Swan Electric Co, Ferguson Pailin, Hotpoint Electric Appliance Co, International Refrigerator Co, Newton Victor, Sunvic Controls, Premier Electric Heaters, Siemens Bros (1955) and Birlec (1954). In 1959 AEI decided to remove the familiar brands of BTH and Metrovicks and consolidate both as AEI resulting in internal problems and a fall in sales and market value. However, AEI acquired a variety of companies from 1959 to 1967, these included Associated Insulation Products, W. T. Henley’s Telegraph Works Co (1958), and London Electric Wire Co and Smiths (1958), Submarine Cables, Hackbridge Holdings Ltd., The Lancashire Dynamo and Crypto Ltd., W.T. Avery Ltd., Henley and Schreiber. The General Electric Company bought AEI in 1967.

Metropolitan-Vickers Electrical Co Ltd was the new trading name given to British Westinghouse Electric and Manufacturing Co on 8 September 1919. The predecessor company had sold its controlling share to the Metropolitan Carriage Wagon Co in 1916 in order to gain membership of the Federation of British Industries. In 1919, Vickers acquired the Metropolitan Carriage Wagon Co, along with its controlling share in British Westinghouse, prompting the change in name to Metropolitan-Vickers Electrical Co Ltd. The American owned British Westinghouse had established its English operations at Trafford Park in 1899, and Metropolitan-Vickers Electrical Co Ltd continued on the same site from 8 September 1919. The company was initially known for its electricity generators, later diversifying into the manufacture of steam turbines, switchgear, transformers, electronics and railway traction equipment. The passing of the Electricity (Supply) Act in 1926 provided a boost to the company’s post-war fortunes, with the creation of the National Grid generating demand for the company's products. In 1928, Metropolitan-Vickers Electrical Co Ltd merged with its rival British Thomson Houston Co Ltd, retaining both names for trading purposes. The following year, on 4 January 1929, Associated Electrical Industries Ltd (AEI) acquired Metropolitan-Vickers Electrical Co Ltd and the British Thomson Houston Co Ltd. Again, both trading names were retained, and a fierce rivalry was established between the firms which the parent company was unable to control. In 1931, Sir Felix Pole joined Metropolitan-Vickers Electrical Co Ltd as its new chairman. He oversaw a period of expansion for the company leading into the Second World War. In 1939, seeking a more concise name for the company, the Board of Directors decided upon Metrovicks, which became interchangeable with the official company name of Metropolitan-Vickers Electrical Co Ltd. Under Sir Felix Pole's chairmanship, Metropolitan-Vickers developed new products for the aviation industry and during the war was one of the sites where Lancaster bombers were built. In 1941, the company developed the first British axial-flow jet engine, the Metrovick F.2. Following the Second World War, the company appointed Oliver Lyttelton as chairman, with the aim of increasing the efficiency and productivity of AEI. Despite his success in achieving this aim, Lyttelton was unable to resolve the commercial rivalry between Metropolitan-Vickers Electrical Co Ltd and the British Thomson Houston Co Ltd. During his second period as chairman, from 1954-1963, Lyttelton, now Lord Chandos, oversaw the development by Metropolitan-Vickers Electrical Co Ltd of the first commercial transistor computer, the Metrovick 950. Chandos also resolved to extinguish the competition and internal divisions between Metropolitan-Vickers Electrical Co Ltd and the British Thomson Houston Co Ltd, and both company names ceased to be used from 1 January 1960, with all subsidiaries going on to trade under the name of Associated Electrical Industries Ltd.
