Richard Henry Morefield (September 9, 1929 – October 11, 2010) served in the United States Foreign Service and was one of the 66 staff members at the American embassy in Tehran who were taken captive by a militant Islamist student group called the Muslim Student Followers of the Imam's Line on November 4, 1979, as part of what became known as the Iran hostage crisis.
He was one of 52 Americans who were held as a hostage for 444 days, until negotiations for the remaining captives being held hostage were concluded with the signing of the Algiers Accords on January 19, 1981, with their release coming the following day.
