Bill Clinton was born "William Jefferson Blythe III" in Hope, Arkansas. His father, William Jefferson Blythe, Jr., was a traveling salesman who died in an automobile accident three months before Bill was born. Bill's mother returned from nursing school and shortly thereafter married Roger Clinton, who together with his brother owned an automobile dealership in Hot Springs, Arkansas. The family moved to Hot Springs in 1950.

Although he assumed use of his stepfather's surname, it was not until Billy (as he was known then) turned fourteen that he formally adopted the surname Clinton, partially as a gesture toward his stepfather.

Clinton served as the 42nd President of the United States, from 1993 to 2001. He was the third-youngest president; only Theodore Roosevelt and John F. Kennedy were younger when entering office. He became president at the end of the Cold War, and as he was born in the period after World War II, he is known as the first Baby Boomer president. His wife, Hillary Rodham Clinton, is currently the United States Secretary of State. She was previously a United States Senator from New York, and also candidate for the Democratic presidential nomination in 2008. Both are graduates of Yale Law School.

Clinton was described as a New Democrat and was largely known for the Third Way philosophy of governance that came to epitomize his two terms as president. His policies, on issues such as the North American Free Trade Agreement and welfare reform, have been described as centrist. Clinton presided over the longest period of peace-time economic expansion in American history, which included a balanced budget and a reported federal surplus.

Based on Congressional accounting rules, at the end of his presidency Clinton reported a surplus of $559 billion. On the heels of a failed attempt at health care reform with a Democratic Congress, Republicans won control of the House of Representatives for the first time in forty years. Two years later, in 1996, Clinton was re-elected and became the first member of the Democratic Party since Franklin D. Roosevelt to win a second term as president. Later he was impeached for obstruction of justice, but was subsequently acquitted by the U.S. Senate.

Clinton left office with an approval rating at 66%, the highest end of office rating of any president since World War II. Since then, he has been involved in public speaking and humanitarian work. Clinton created the William J. Clinton Foundation to promote and address international causes such as treatment and prevention of HIV/AIDS and global warming.

In 2004, he released his autobiography, My Life, and more recently has been involved in his wife Hillary's 2008 presidential campaign and in that of President Barack Obama. In 2009, he was named United Nations Special Envoy to Haiti.
