( 1914–2002), Norwegian anthropologist. He is noted for his ocean voyages in primitive craft to demonstrate his theories of cultural diffusion, the best known of which was that of the balsa raft Kon-Tiki from Peru to the islands east of Tahiti in 1947. In 1969, he successfully crossed from Morocco to Central America in a papyrus boat (Ra II).
