The Institute was founded by a group of key figures from the Tavistock Clinic and British Army psychiatry including Elliott Jaques, Henry Dicks, Leonard Browne, Ronald Hargreaves, John Rawlings Rees, Mary Luff and Wilfred Bion, with Tommy Wilson as chairman. Other well-known people that joined the group shortly after were Isabel Menzies Lyth, J. D. Sutherland, John Bowlby, Eric Trist, and Fred Emery. Although he died before the TIHR was formally established, Kurt Lewin was an important influence on the work of the Tavistock: he was a notable influence on Trist, and contributed an article to the first issue of "Human Relations".
