Kofi Atta Annan was a Ghanaian diplomat who served as the seventh secretary-general of the United Nations from 1997 to 2006. Annan and the UN were the co-recipients of the 2001 Nobel Peace Prize. He was the founder and chairman of the Kofi Annan Foundation, as well as chairman of The Elders, an international organisation founded by Nelson Mandela.
Annan joined the United Nations in 1962, working for the World Health Organization's Geneva office. He went on to work in several capacities at the UN Headquarters, including serving as the under-secretary-general for peacekeeping between March 1992 and December 1996. He was appointed secretary-general on 13 December 1996 by the Security Council and later confirmed by the General Assembly, making him the first officeholder to be elected from the UN staff itself. He was re-elected for a second term in 2001 and was succeeded as secretary-general by Ban Ki-moon in 2007.
As secretary-general, Annan reformed the UN bureaucracy, worked to combat HIV/AIDS and launched the UN Global Compact.
