He took a second degree at Uppsala in economics, in 1928, a law degree in 1930, and a doctoral degree in economics in 1934.
In the six years after his first major victory of 1954-1955, when he personally negotiated the release of American soldiers captured by the Chinese in the Korean War, he was involved in struggles on three of the world's continents.

Hammarskjöld represented Sweden as a delegate to the United Nations in 1949 and again from 1951 to 1953.
Receiving fifty-seven votes out of sixty, Hammarskjöld was elected Secretary-General of the United Nations in 1953 for a five-year term and reelected in 1957.
