Hanson Trust was formed in 1964 by James Hanson and Gordon White. It rapidly grew by acquisition and became a multinational concern with interests in chemicals, construction, energy, tobacco and other industries. Over the years, Hanson shifted its focus to construction materials and sold its non-core business. By 2006, Hanson PLC had become the world’s largest producer of aggregates. HeidelbergCement acquired Hanson in 2007 and integrated its North American operations with the Lehigh Cement Company. The Lehigh and Hanson business units in North America are collectively known as Lehigh Hanson, Inc.
