The second Secretary-General of the United Nations, he served from April 1953 until his death in a plane crash in September 1961. He is one of four people to have been awarded a posthumous Nobel Peace Prize. Hammarskjöld remains the only U.N. Secretary-General to die in office, and his death occurred en route to cease-fire negotiations. American President John F. Kennedy called Hammarskjöld “the greatest statesman of our century".

Dag Hammarskjöld was born in Jönköping, Sweden, but spent most of his childhood in Uppsala. The fourth and youngest son of Hjalmar Hammarskjöld, Prime Minister of Sweden from 1914 to 1917, and Agnes Hammarskjöld (née Almquist), Hammarskjöld's ancestors served the Monarchy of Sweden since the 17th century. He studied first at Katedralskolan and then at Uppsala University where he graduated with a Bachelor of Laws and a Master's degree in Political economy. During this time he served for a year as the first Curator at Uplands Nation later moving to Stockholm.
