Background: Ban Ki-moon (; Hangul: bangimun; Hanja: Pan Ji Wen ; Korean pronunciation: [pan.gi.mun]; born 13 June 1944) is a South Korean diplomat who was the eighth Secretary-General of the United Nations from January 2007 to December 2016. Before becoming Secretary-General, Ban was a career diplomat in South Korea's Ministry of Foreign Affairs and in the United Nations. He entered diplomatic service the year he graduated from university, accepting his first post in New Delhi, India.
Context: Ban was born on 13 June 1944 in the small farming village of Haengchi, Wonnam Township (-myeon), in Eumseong County, North Chungcheong Province in Korea. His family then moved to the nearby town of Chungju, where he grew up. During Ban's childhood, his father had a warehouse business, but the warehouse went bankrupt and the family lost its middle-class standard of living. When Ban was six, his family fled to a remote mountainside for much of the Korean War. After the war ended, his family returned to Chungju. Ban has said that, during this time, he met American soldiers.  In secondary school (Chungju High School), Ban became a star student, particularly in his studies of the English language. In 1962, Ban won an essay contest sponsored by the Red Cross and earned a trip to the United States where he lived in San Francisco with a host family for several months. As part of the trip, Ban met U.S. President John F. Kennedy. When a journalist at the meeting asked Ban what he wanted to be when he grew up, he said, "I want to become a diplomat."  He received a bachelor's degree in international relations from Seoul National University in 1970, and earned a Master of Public Administration from the John F. Kennedy School of Government at Harvard University in 1985. At Harvard, he studied under Joseph Nye, who remarked that Ban had "a rare combination of analytic clarity, humility and perseverance". Ban was awarded the degree of Doctor of Laws (Honoris Causa) by the University of Malta on 22 April 2009. He further received an honorary degree of Doctor of Laws from the University of Washington in October 2009, an honorary degree of Doctor of Law from the University of Cambridge in February 2016, and an Honorary Doctor of Humane Letters Degree from Loyola Marymount University in April 2016. On 30 August 2016, he was conferred the Honorary Doctor of Letters by National University of Singapore for his lifetime of service to humanity.  In addition to his native Korean, Ban speaks English and French. According to a retired UN official, "one of Ban's biggest handicaps was his lack of fluency in English, which made it difficult for him to win over audiences in the US and elsewhere." There have also been questions, however, regarding the extent of his knowledge of French, one of the two working languages of the United Nations Secretariat.
