Arne Sund (born 14 August 1925,[1] died 4 December 2011[2]) was a Norwegian military psychiatrist.
He became a captain of the Norwegian Armed Forces medical service in 1955 and a lieutenant-colonel and chief psychiatrist in 1967.
His own experiences from several war and conflict areas, both with stress reactions among soldiers and with the suffering of the civilian population, had great influence on his later work as a psychiatrist.
[3] Through Sund's efforts Norway became "an international pioneer in the research on mass killings, war, catastrophes, accidents and all forms of violence.
"[2] In 1978 he was appointed as Professor of Disaster Psychiatry at the University of Oslo and the founding director of the Division of Disaster Psychiatry, a joint unit of the University of Oslo Faculty of Medicine and the Norwegian Armed Forces medical service.
