Major Tom Harnett Harrisson, DSO, OBE[1] (26 September 1911 – 16 January 1976) was a British polymath. In the course of his life he was an ornithologist, explorer, journalist, broadcaster, soldier, guerrilla, ethnologist, museum curator, archaeologist, documentarian, film-maker, conservationist and writer. Although often described as an anthropologist, and sometimes referred to as the "Barefoot Anthropologist", his degree studies at University of Cambridge, before he left to live in Oxford, were in natural sciences. He was a founder of the social observation organisation Mass-Observation. He conducted ornithological and anthropological research in Sarawak (1932) and the New Hebrides (1933–35), spent much of his life in Borneo (mainly Sarawak) and finished up in the US, the UK and France, before dying in a road accident in Thailand.
