present Chairman of Jardine Matheson Holdings Ltd, Sir Henry Keswick, who is based in the UK, was the company's tai-pan from 1970 (aged 31) to 1975 and was the 6th Keswick to be tai-pan of the company. His brother Simon was the company's taipan from 1983 to 1988 and is the 7th Keswick to be tai-pan. Both brothers are the 4th generation of Keswicks in the company. The organizational structure of Jardines has changed almost totally, but members of Jardine's family still control the firm through a complex cross-shareholding structure, several allied shareholders and a secretive 1947 Trust.
