Graham Anderson Martin was an American diplomat. He was the ambassador to Thailand and as U.S. representative to SEATO from 1963 to 1967, ambassador to Italy from 1969 to 1973 and the last United States Ambassador to South Vietnam from 1973 until his evacuation during the Fall of Saigon in 1975.

Operation Frequent Wind was the final phase in the evacuation of American civilians and "at-risk" Vietnamese from Saigon, South Vietnam, before the takeover of the city by the North Vietnamese People's Army of Vietnam (PAVN) in the Fall of Saigon. It was carried out on 29–30 April 1975, during the last days of the Vietnam War. More than 7,000 people were evacuated by helicopter from various points in Saigon. The airlift resulted in a number of enduring images.
