Hanson UK, formerly Hanson Trust plc, is a British-based building materials company, headquartered in Maidenhead. The company has been a subsidiary of the German company HeidelbergCement since August 2007, and was formerly listed on the London Stock Exchange and a constituent of the FTSE 100 Index. History Hanson was built up by James Hanson, later Lord Hanson, and Gordon White, later Baron White of Hull, who set up Hanson Trust in 1964. Hanson and White were willing to take a wide range of measures to do so, including mass redundancies, and therefore attracted opposition and accusations that they were asset strippers, but from 1979, the company was successful from the shareholders' point of view and respected during the early 1980s, with Hanson (who gave millions of pounds to the Conservatives) admired by Margaret Thatcher. One of the most notable takeovers, at least to the general public, was the acquisition in 1983, of the United Drapery Stores, or UDS Group, which owned many of Britain's most well known high street clothes shops and department stores, including John Collier, Richard Shops and the chain of Allders department stores. To fund this purchase, Hanson broke up UDS and sold John Collier to a management buy out team, and Richard Shops to Habitat, keeping only the core department store business. In January 1986, Hanson bought SCM, an American chemicals to typewriters business. This included the paper division that was formerly the Allied Paper Corporation. Hanson sold most of the SCM business units and the headquarters building in New York City for a significant profit. Its most significant single purchase, however, was probably its takeover of Imperial Tobacco Group in 1986. Hanson paid £2.5 billion for the group then undertook a major reorganisation; divestitures netted £2.3 billion, leaving Hanson with the hugely profitable tobacco business for "next to nothing." Hanson sold off the food brand, Golden Wonder, to Dalgety plc in 1986. In November 1988, Hanson went on to buy Consolidated Gold Fields for £3.5bn. The Gold Survey was taken on by a new company, now known as GFMS. An attempt in September 1991, to purchase Imperial Chemical Industries, once seen by many in Britain as the nation's leading company but then in decline, was highly controversial, and ended in failure. Hanson did secure the takeover of Beazer, a major housebuilder, that year. By the mid-1990s, conglomerates were no longer popular with the investment community.
