Dag Hjalmar Agne Carl Hammarskjöld was the Secretary-General of the United Nations from 10 April 1953 until 18 September 1961, when he died in a plane crash while on a peace mission in the Congo. He was born on 29 July 1905 in Jönköping in south-central Sweden.
Serving two terms as the UN chief, the man many considered to be the peacemaker of the 20th century carried out a wide range of responsibilities in the course of efforts to prevent war and serve the other aims of the UN Charter.
As new evidence emerges about his death, UN Photo curated a collection from our archive depicting the man, the legend and the Secretary-General.
“Never, for the sake of peace and quiet, deny your own experience or convictions.” - Dag Hammarskjöld, second Secretary-General of the United Nations.

"It will not surprise you to hear that Dag Hammarskjöld is a figure of great importance to me - as he must be for any Secretary-General. His life and his death, his words and his action have done more to shape public expectations of the office, and indeed of the Organization, than those of any other man or woman in its history." - UN Secretary-General Kofi Annan, 6 September 2001
