The Kon-Tiki Museum in Oslo contains the balsawood raft that was used by Thor Heyerdahl in his famous 1947 journey from Peru to Polynesia. The Kon-Tiki Expedition was conducted to prove that such a journey could be undertaken with pre-Inca technology and know-how. Heyerdahl wanted to prove his theory that the original Polynesian settlers had sailed in such rafts from Peru.
Thor Heyerdahl (October 6, 1914, Larvik, Norway – April 18, 2002, Colla Micheri, Italy) was a Norwegian ethnographer and adventurer with a background in zoology and geography. He became notable for his Kon-Tiki expedition, in which he sailed 8,000 km (5,000 mi) across the Pacific Ocean in a self-built raft from South America to the Tuamotu Islands in 1947.
