The Scottish author Robert Louis Stevenson (1850–94) lived principally on Upolu from 1889 until his death. Samoans famous since independence include Malietoa Tanumafili II (b.1913), who was named head of state in 1962, and Fiame Faumuina Mataafa (d.1975), who served as prime minister from 1962 to 1970 and again from 1973 until his death. Tupuola Taisi Efi (b.1938), was prime minister from 1976 to 1982. Tofilau Eti (b. American Samoa, 1925?) was prime minister from December 1982 to December 1985, when he resigned and was succeeded by Va'ai Kolone.
