Thor Heyerdahl (1914 – 2002) was a Norwegian ethnographer and adventurer with a scientific background in zoology and geography.
After an expedition (1936) to the French Marquesas (Fatu Hiva) with his wife living for 1 year on a lost island, he became famous for his Kon-Tiki
expedition (1947), in which he sailed 4,300 miles (7,000 km) by raft from Peru to the Tuamotu Islands.
Thus, Kon-Tiki demonstrated that it was possible for a primitve raft to sail the Pacific with relative ease and that Polynesia could have been settled from east to west, whereas usually anthropologists continue to believe that Polynesia was settled from west to east, migration having begun from Asia.
