Thor Heyerdahl (1914–2002), the Norwegian ethnographer and archaeologist. A passion for geographic research—“he took it from his great countrymen, Fridtjof Nansen and Roald Amundsen.” His first journeys (to the Marquesas Islands and to British Columbia) were made while he was still young. He took part in the Second World War—serving as a radio operator in a sabotage unit. In 1947 the world held its breath as it watched the daring voyage of a group of enthusiasts on the Kon-Tiki raft across the eastern part of the Pacific Ocean. After that came expeditions aboard the papyrus boat Ra across the Atlantic, the reed vessel Tigris through the Persian Gulf, the Arabian Sea, and the Red Sea. And there were also journeys to the Maldives, to Easter Island, an archaeological expedition in Peru… In his books about his expeditions, Thor Heyerdahl achieved worldwide fame—including, of course, in our country.
