His career is one lined with high responsibility posts in matters of government. From 1935 to 1941, Dag was the secretary of the Riksbank (the central bank of Sweden). Then he became the State Secretary in the Ministry of Finance from 1936 to 1945. He held the post of Governor of the Riksbank in 1941 to 1948. He then was placed as the Swedish delegate in the OEEC (Organization for European Economic Cooperation) from 1947 to 1953. For two years from 1949 to 1951 he was known as Cabinet Secretary in the Ministry of Foreign Affairs and then for the next two years as minister without portfolio in Tage Erlander's government from 1951 to 1953. It was in the year of 1953 that he would be given task and responsibility for his final post.
Dag's election as the general secretary of the UN (United Nations) was supported by the fact that although he sat in the Swedish government, he was not aligned to any specific political party. He was a Swede and Sweden's neutral policy during the World Wars made a Swede allies with many countries. This Swede was also known to be fluent in not only Swedish, yet also English, French and German.
This great Swede was awarded the Nobel Peace Prize in 1961, posthumously.
Duty and spiritual maturity are stated as having been key elements of his life. This public servant had high standards and expected peak performance from his colleagues. As an intellectual he was well quipped to write his own speeches, however he tended to give speeches that were formal, rigid and monotonically (in the same tone) as he frowned on exaggerated gestures and other ways as being staged.
His high sense of responsibility and sense of work commitment seems to have left no room for any romantic relationships. There is no record of any marriage, intimate relationships and consequently children.
Photography was one of his pastimes, while participating in his many travels. This man was known to have read extensively and been involved in translations of works of literature. Dag is regarded as having an inspiring amount of self-discipline.
The cause of that fatal crash above Africa has never been solved;speculation includes human error, technical error in the plane, sabotage or some form of attack. His remains are buried in the family grave at an Uppsala old cemetery.
