Jimmy Carter is a published author and Nobel Peace Prize winner, but he is most famous for being the 39th President of the United States. Carter served as President from Jan. 20, 1977 to Jan. 20, 1981.
Prior to announcing his candidacy for president, Jimmy Carter was a governor and senator in the state of Georgia. He was elected president on Nov. 2, 1976, and he served just one term before President Ronald Regan took office. Carter had very high approval ratings when he first assumed office, but his approval ratings declined dramatically during the Iran Hostage Crisis. During this crisis, 66 Americans were held hostage by Iranian citizens who felt they were betrayed by Carter, who granted Iran's overthrown leader, Mohammad Reza Pahlavi, access to the United States. The hostages were released on the day Ronald Regan assumed office.
Following his presidency, Carter worked extensively with Habitat for Humanity and started an organization called The Carter Center, which promotes human rights and helps to alleviate hunger, disease and other forms of suffering worldwide. Carter also helped to develop numerous community-based health care facilities in Africa, Latin America and other less-fortunate countries. Carter's humanitarian efforts earned him a Nobel Peace Prize in 2002. Carter is also the author of 28 books.
