Thor Heyerdahl, explorer, anthropologist and adventurer, is well-known for his daring expedition around the globe. Almost half a century ago he risked his life sailing from Peru to Polynesia on a balsa raft, the story immortalized in his book The Kon-Tiki Expedition (1948). Since then similar voyages have taken him across the Atlantic and Indian Oceans, and the most remote corners of the world, in a lifelong quest for knowledge, adventure and excitement.
