Thor Heyerdahl (Norwegian pronunciation: [tuːr hæiːərdɑːl]; October 6, 1914 – April 18, 2002) was a Norwegian ethnographer and adventurer with a background in biology, zoology, botany, and geography. He became notable for his Kon-Tiki expedition in 1947, in which he sailed 8,000 km (5,000 mi) across the Pacific Ocean in a hand-built raft from South America to the Tuamotu Islands. The expedition was designed to demonstrate that ancient people could have made long sea voyages, creating contacts between separate cultures. This was linked to a diffusionist model of cultural development. Heyerdahl subsequently made other voyages designed to demonstrate the possibility of contact between widely separated ancient peoples. He was appointed a government scholar in 1984.
In May 2011, the Thor Heyerdahl Archives were added to UNESCO's "Memory of the World" Register. At the time, this list included 238 collections from all over the world. The Heyerdahl Archives span the years 1937 to 2002 and include his photographic collection, diaries, private letters, expedition plans, articles, newspaper clippings, original book, and article manuscripts. The Heyerdahl Archives are administered by the Kon-Tiki Museum and the National Library of Norway in Oslo.

Youth and personal life
Heyerdahl was born in Larvik, Norway, the son of master brewer Thor Heyerdahl and his wife, Alison Lyng. As a young child, Heyerdahl showed a strong interest in zoology. He created a small museum in his childhood home, with a Vipera berus as the main attraction. He studied zoology and geography at the faculty of biological science at the University of Oslo. At the same time, he privately studied Polynesian culture and history, consulting what was then the world's largest private collection of books and papers on Polynesia, owned by Bjarne Kropelien, a wealthy wine merchant in Oslo. This collection was later purchased by the University of Oslo Library from Kropelien's heirs and was attached to the Kon-Tiki Museum research department. After seven terms and consultations with experts in Berlin, a project was developed and sponsored by Heyerdahl's zoology professors, Kristine Bonnevie and Hjalmar Broch. He was to visit some isolated Pacific island groups and study how the local animals had found their way there.
Just before sailing together to the Marquesas Islands in 1936, Heyerdahl married his first wife, Liv Coucheron-Torp (1916–1969), whom he had met shortly before enrolling at the university, and who had studied economics there. The couple had two sons; Thor Jr and Bjørn. The marriage ended in divorce.
In 1949 Heyerdahl married Yvonne Dedekam-Simonsen (1924–2006). They had three daughters: Annette, Marian and Helene Elisabeth. They were divorced in 1969. Heyerdahl blamed their separation on his being away from home and differences in their ideas for bringing up children. In his autobiography, he concluded that he should take the entire blame for their separation.
In 1991, Heyerdahl married Jacqueline Beer (born 1932) as his third wife. They lived in Tenerife, Canary Islands and were very actively involved with archaeological projects, especially in Túcume, Peru, and Azov until his death in 2002. He still had been hoping to undertake an archaeological project in Samoa before he died.
Heyerdahl died on April 18, 2002, in Colla Micheri, Liguria, Italy, where he had gone to spend the Easter holidays with some of his closest family members. The Norwegian government gave him a state funeral in Oslo Cathedral on April 26, 2002. He is buried in the garden of the family home in Colla Micheri.
The events surrounding his stay on the Marquesas, most of the time on Fatu Hiva, were told first in his book På Jakt etter Paradiset (Hunt for Paradise) (1938), which was published in Norway but, following the outbreak of World War II, never translated and largely forgotten. Many years later, having achieved notability with other adventures and books on other subjects, Heyerdahl published a new account of this voyage under the title Fatu Hiva (London: Allen & Unwin, 1974). The story of his time on Fatu Hiva and his side trip to Hivaoa and Mohotani is also related in Green Was the Earth on the Seventh Day (Random House, 1996).
In 1947, Heyerdahl and five fellow adventurers sailed from Peru to the Tuamotus, French Polynesia, in a pae-pae raft they constructed from balsa wood and other native materials, and christened the Kon-Tiki. The Kon-Tiki expedition was inspired by old reports and drawings made by the Spanish Conquistadors of Inca rafts, and by native legends and archaeological evidence suggesting contact between South America and Polynesia. On August 7, 1947, after a 101-day, 4,300 nautical mile (4,948 miles or 7,964 km) journey across the Pacific Ocean, the Kon-Tiki smashed into the reef at Raroia in the Tuamotu Islands. Heyerdahl, who had nearly drowned at least twice in childhood and did not take easily to water, said later that there were times in each of his raft voyages when he feared for his life.
Kon-Tiki demonstrated that it was possible for a primitive raft to sail the Pacific with relative ease and safety, especially to the west (with the trade winds). The raft proved to be highly maneuverable, and fish congregated between the nine balsa logs in such numbers that ancient sailors could have possibly relied on fish for hydration in the absence of other sources of fresh water. Inspired by Kon-Tiki, other rafts have repeated the voyage. Heyerdahl's book about the expedition, The Kon-Tiki Expedition: By Raft Across the South Seas, has been translated into 70 languages. The documentary film of the expedition, itself entitled Kon-Tiki, won an Academy Award in 1951. A dramatised version was released in 2012, also called Kon-Tiki, and was nominated for both the Best Foreign Language Oscar at the 85th Academy Awards and a Golden Globe Award for Best Foreign Language Film at the 70th Golden Globe Awards. It is the first time a Norwegian film has been nominated for both an Oscar and a Golden Globe.
Anthropologists continue to believe, based on linguistic, physical, and genetic evidence, that Polynesia was settled from west to east, migration having begun from the Asian mainland. There are controversial indications, though, of some sort of South American/Polynesian contact, most notably in the fact that the South American sweet potato is served as a dietary staple throughout much of Polynesia. Blood samples taken in 1971 and 2008 from Easter Islanders without any European or other external descent were analysed in a 2011 study, which concluded that the evidence supported some aspects of Heyerdahl's hypothesis. Heyerdahl attempted to counter the linguistic argument with the analogy that, guessing the origin of African-Americans, he would prefer to believe that they came from Africa, judging from their skin colour, and not from England, judging from their speech.
Theory on Polynesian origins
Heyerdahl claimed that in Incan legend there was a sun-god named Con-Tici Viracocha who was the supreme head of the mythical fair-skinned people in Peru. The original name for Viracocha was Kon-Tiki or Illa-Tiki, which means Sun-Tiki or Fire-Tiki. Kon-Tiki was high priest and sun-king of these legendary "white men" who left enormous ruins on the shores of Lake Titicaca. The legend continues with the mysterious bearded white men being attacked by a chief named Cari who came from the Coquimbo Valley. They had a battle on an island in Lake Titicaca, and the fair race was massacred. However, Kon-Tiki and his closest companions managed to escape and later arrived on the Pacific coast. The legend ends with Kon-Tiki and his companions disappearing westward out to sea.
When the Spaniards came to Peru, Heyerdahl asserted, the Incas told them that the colossal monuments that stood deserted about the landscape were erected by a race of white gods who had lived there before the Incas themselves became rulers. The Incas described these "white gods" as wise, peaceful instructors who had originally come from the north in the "morning of time" and taught the Incas' primitive forefathers architecture as well as manners and customs. They were unlike other Native Americans in that they had "white skins and long beards" and were taller than the Incas. The Incas said that the "white gods" had then left as suddenly as they had come and fled westward across the Pacific. After they had left, the Incas themselves took over power in the country.
Heyerdahl said that when the Europeans first came to the Pacific islands, they were astonished that they found some of the natives to have relatively light skins and beards. There were whole families that had pale skin, hair varying in color from reddish to blonde. In contrast, most of the Polynesians had golden-brown skin, raven-black hair, and rather flat noses. Heyerdahl claimed that when Jakob Roggeveen first discovered Easter Island in 1722, he supposedly noticed that many of the natives were white-skinned. Heyerdahl claimed that these people could count their ancestors who were "white-skinned" right back to the time of Tiki and Hotu Matua, when they first came sailing across the sea "from a mountainous land in the east which was scorched by the sun." The ethnographic evidence for these claims is outlined in Heyerdahl's book Aku Aku: The Secret of Easter Island.
Heyerdahl proposed that Tiki's neolithic people colonized the then-uninhabited Polynesian islands as far north as Hawaii, as far south as New Zealand, as far east as Easter Island, and as far west as Samoa and Tonga around 500 AD. They supposedly sailed from Peru to the Polynesian islands on pae-paes—large rafts built from balsa logs, complete with sails and each with a small cottage. They built enormous stone statues carved in the image of human beings on Pitcairn, the Marquesas, and Easter Island that resembled those in Peru. They also built huge pyramids on Tahiti and Samoa with steps like those in Peru. But all over Polynesia, Heyerdahl found indications that Tiki's peaceable race had not been able to hold the islands alone for long. He found evidence that suggested that seagoing war canoes as large as Viking ships and lashed together two and two had brought Stone Age Northwest American Indians to Polynesia around 1100 AD, and they mingled with Tiki's people. The oral history of the people of Easter Island, at least as it was documented by Heyerdahl, is completely consistent with this theory, as is the archaeological record he examined (Heyerdahl 1958). In particular, Heyerdahl obtained a radiocarbon date of 400 AD for a charcoal fire located in the pit that was held by the people of Easter Island to have been used as an "oven" by the "Long Ears," which Heyerdahl's Rapa Nui sources, reciting oral tradition, identified as a white race which had ruled the island in the past (Heyerdahl 1958).
Heyerdahl further argued in his book American Indians in the Pacific that the current inhabitants of Polynesia migrated from an Asian source, but via an alternate route. He proposes that Polynesians travelled with the wind along the North Pacific current. These migrants then arrived in British Columbia. Heyerdahl called contemporary tribes of British Columbia, such as the Tlingit and Haida, descendants of these migrants. Heyerdahl claimed that cultural and physical similarities existed between these British Columbian tribes, Polynesians, and the Old World source. Heyerdahl's claims aside, however, there is no evidence that the Tlingit, Haida or other British Columbian tribes have an affinity with Polynesians.
Heyerdahl's theory of Polynesian origins have not gained acceptance among anthropologists. Physical and cultural evidence had long suggested that Polynesia was settled from west to east, migration having begun from the Asian mainland, not South America. In the late 1990s, genetic testing found that the mitochondrial DNA of the Polynesians is more similar to people from southeast Asia than to people from South America, showing that their ancestors most likely came from Asia.
A recent study by Norwegian researcher Erik Thorsby suggests that there is some merit to Heyerdahl's ideas and that while Polynesia was colonized from Asia, some contact with South America also existed. Some critics suggest, however, that Thorsby's research is inconclusive because his data may have been influenced by recent population contact.
Anthropologist Robert Carl Suggs included a chapter titled "The Kon-Tiki Myth" in his book on Polynesia, concluding that "The Kon-Tiki theory is about as plausible as the tales of Atlantis, Mu, and 'Children of the Sun.' Like most such theories it makes exciting light reading, but as an example of scientific method it fares quite poorly."
Anthropologist and National Geographic Explorer-in-Residence Wade Davis also criticised Heyerdahl's theory in his book The Wayfinders, which explores the history of Polynesia. Davis says that Heyerdahl "ignored the overwhelming body of linguistic, ethnographic, and ethnobotanical evidence, augmented today by genetic and archaeological data, indicating that he was patently wrong."
Expedition to Rapa Nui (Easter Island)
In 1955–1956, Heyerdahl organized the Norwegian Archaeological Expedition to Rapa Nui (Easter Island). The expedition's scientific staff included Arne Skjølsvold, Carlyle Smith, Edwin Ferdon, Gonzalo Figueroa and William Mulloy. Heyerdahl and the professional archaeologists who traveled with him spent several months on Rapa Nui investigating several important archaeological sites. Highlights of the project include experiments in the carving, transport and erection of the notable moai, as well as excavations at such prominent sites as Orongo and Poike. The expedition published two large volumes of scientific reports (Reports of the Norwegian Archaeological Expedition to Easter Island and the East Pacific) and Heyerdahl later added a third (The Art of Easter Island). Heyerdahl's popular book on the subject, Aku-Aku was another international best-seller.
In Easter Island: The Mystery Solved (Random House, 1989), Heyerdahl offered a more detailed theory of the island's history. Based on native testimony and archaeological research, he claimed the island was originally colonized by Hanau eepe ("Long Ears"), from South America, and that Polynesians Hanau momoko ("Short Ears") arrived only in the mid-16th century; they may have come independently or perhaps were imported as workers. According to Heyerdahl, something happened between Admiral Roggeveen's discovery of the island in 1722 and James Cook's visit in 1774; while Roggeveen encountered white, Indian, and Polynesian people living in relative harmony and prosperity, Cook encountered a much smaller population consisting mainly of Polynesians and living in privation.
Heyerdahl notes the oral tradition of an uprising of "Short Ears" against the ruling "Long Ears." The "Long Ears" dug a defensive moat on the eastern end of the island and filled it with kindling. During the uprising, Heyerdahl claimed, the "Long Ears" ignited their moat and retreated behind it, but the "Short Ears" found a way around it, came up from behind, and pushed all but two of the "Long Ears" into the fire. This moat was found by the Norwegian expedition and it was partly cut down into the rock. Layers of fire was revealed but no fragments of bodies. This were two shafts of around 10 meters length of the overall 3000 meter for the whole moat. As for the origin of the people of Easter Island today (2013) DNA-tests have shown a total agreement with people from the Pacific and no connection to South America. If the story that all (almost) long-ears were killed in a civil war, this is what to be expected if their blood-line was totally destroyed. Recent (2006?) test has shown traces to South America from some proteins, but if this is inherited from a person coming in later times is hard to know.
Boats Ra and Ra II
In 1969 and 1970, Heyerdahl built two boats from papyrus and attempted to cross the Atlantic Ocean from Morocco in Africa. Based on drawings and models from ancient Egypt, the first boat, named Ra (after the Egyptian Sun god), was constructed by boat builders from Lake Chad using papyrus reed obtained from Lake Tana in Ethiopia and launched into the Atlantic Ocean from the coast of Morocco. The Ra crew included Thor Heyerdahl (Norway), Norman Baker (USA), Carlo Mauri (Italy), Yuri Senkevich (USSR), Santiago Genoves (Mexico), Georges Sourial (Egypt) and Abdullah Djibrine (Chad). Only Heyerdahl and Baker had sailing and navigation experiences. After a number of weeks, Ra took on water after its crew made modifications to the vessel that caused it to sag and break apart after sailing more than 4000 miles. The crew was forced to abandon Ra some hundred miles before Caribbean islands and was saved by a yacht.
The following year, 1970, another similar vessel, Ra II, was built of totora by Demetrio, Juan and Jose Limachi from Lake Titicaca in Bolivia and likewise set sail across the Atlantic from Morocco, this time with great success. The crew was mostly the same; only Djibrine had been replaced by Kei Ohara from Japan and Madani Ait Ouhanni from Morocco. The boat reached Barbados, thus demonstrating that mariners could have dealt with trans-Atlantic voyages by sailing with the Canary Current.
The book The Ra Expeditions and the film documentary Ra (1972) were made about the voyages. Apart from the primary aspects of the expedition, Heyerdahl deliberately selected a crew representing a great diversity in race, nationality, religion and political viewpoint in order to demonstrate that at least on their own little floating island, people could cooperate and live peacefully. Additionally, the expedition took samples of marine pollution and presented their report to the United Nations.
Heyerdahl built yet another reed boat, Tigris, which was intended to demonstrate that trade and migration could have linked Mesopotamia with the Indus Valley Civilization in what is now Pakistan. Tigris was built in Iraq and sailed with its international crew through the Persian Gulf to Pakistan and made its way into the Red Sea. After about five months at sea and still remaining seaworthy, the Tigris was deliberately burnt in Djibouti, on April 3, 1978, as a protest against the wars raging on every side in the Red Sea and Horn of Africa. In his Open Letter to the UN Secretary-General Kurt Waldheim, he explained his reasons:
Today we burn our proud ship ... to protest against inhuman elements in the world of 1978 ... Now we are forced to stop at the entrance to the Red Sea. Surrounded by military airplanes and warships from the world's most civilized and developed nations, we have been denied permission by friendly governments, for reasons of security, to land anywhere, but in the tiny, and still neutral, Republic of Djibouti. Elsewhere around us, brothers and neighbors are engaged in homicide with means made available to them by those who lead humanity on our joint road into the third millennium.
To the innocent masses in all industrialized countries, we direct our appeal. We must wake up to the insane reality of our time ... We are all irresponsible, unless we demand from the responsible decision makers that modern armaments must no longer be made available to people whose former battle axes and swords our ancestors condemned.Our planet is bigger than the reed bundles that have carried us across the seas, and yet small enough to run the same risks unless those of us still alive open our eyes and minds to the desperate need of intelligent collaboration to save ourselves and our common civilization from what we are about to convert into a sinking ship.
In the years that followed, Heyerdahl was often outspoken on issues of international peace and the environment. The Tigris was crewed by eleven men: Thor Heyerdahl (Norway), Norman Baker (USA), Carlo Mauri (Italy), Yuri Senkevich (USSR), Germán Carrasco (Mexico), Hans Petter Bohn (Norway), Rashad Nazar Salim (Iraq), Norris Brock (USA), Toru Suzuki (Japan), Detlef Zoltze (Germany), and Asbjørn Damhus (Denmark).
"The Search for Odin" in Azerbaijan and Russia
Heyerdahl made four visits to Azerbaijan in 1981, 1994, 1999 and 2000. Heyerdahl had long been fascinated with the rock carvings that date back to about 8th-7th millennia BCE at Gobustan (about 30 miles west of Baku). He was convinced that their artistic style closely resembles the carvings found in his native Norway. The ship designs, in particular, were regarded by Heyerdahl as similar and drawn with a simple sickle–shaped lines, representing the base of the boat, with vertical lines on deck, illustrating crew or, perhaps, raised oars.
Based on this and other published documentation, Heyerdahl proposed that Azerbaijan was the site of an ancient advanced civilization. He believed natives migrated north through waterways to present-day Scandinavia using ingeniously constructed vessels made of skins that could be folded like cloth. When voyagers traveled upstream, they conveniently folded their skin boats and transported them via pack animals.
On Heyerdahl's visit to Baku in 1999, he lectured at the Academy of Sciences about the history of ancient Nordic Kings. He spoke of a notation made by Snorri Sturluson, a 13th-century historian-mythographer in Ynglinga Saga which relates that "Odin (a Scandinavian god who was one of the kings) came to the North with his people from a country called Aser." (see also House of Ynglings and Mythological kings of Sweden). Heyerdahl accepted Snorri's story as literal truth, and believed that a chieftain led his people in a migration from the east, westward and northward through Saxony, to Fyn in Denmark, and eventually settling in Sweden. Heyerdahl claimed that the geographic location of the mythic Aser or Æsir matched the region of contemporary Azerbaijan - "east of the Caucasus mountains and the Black Sea". "We are no longer talking about mythology," Heyerdahl said, "but of the realities of geography and history. Azerbaijanis should be proud of their ancient culture. It is just as rich and ancient as that of China and Mesopotamia."
One of the last projects of his life, Jakten på Odin, 'The Search for Odin', was a sudden revision of his Odin hypothesis, in furtherance of which he initiated 2001–2002 excavations in Azov, Russia, near the Sea of Azov at the northeast of the Black Sea. He searched for the remains of a civilization to match the account of Odin in Snorri Sturlusson, quite a bit north of his original target of Azerbaijan on the Caspian Sea only two years earlier. This project generated harsh criticism and accusations of pseudo-science from historians, archaeologists and linguists in Norway, who accused Heyerdahl of selective use of sources, and a basic lack of scientific methodology in his work.
His central claims were based on similarities of names in Norse mythology and geographic names in the Black Sea region, e.g. Azov and Æsir, Udi and Odin, Tyr and Turkey. Philologists and historians reject these parallels as mere coincidences, and also anachronisms, for instance the city of Azov did not have that name until over 1000 years after Heyerdahl claims the Æsir dwelt there. The controversy surrounding the Search for Odin project was in many ways typical of the relationship between Heyerdahl and the academic community. His theories rarely won any scientific acceptance, whereas Heyerdahl himself rejected all scientific criticism and concentrated on publishing his theories in popular books aimed at the general public.
As of 2012[update], Heyerdahl's Odin hypothesis has yet to be validated by any historian, archaeologist or linguist.
Heyerdahl also investigated the mounds found on the Maldive Islands in the Indian Ocean. There, he found sun-oriented foundations and courtyards, as well as statues with elongated earlobes. Heyerdahl believed that these finds fit with his theory of a seafaring civilization which originated in what is now Sri Lanka, colonized the Maldives, and influenced or founded the cultures of ancient South America and Easter Island. His discoveries are detailed in his book, "The Maldive Mystery."
In 1991 he studied the Pyramids of Güímar on Tenerife and declared that they were not random stone heaps but pyramids. Based on the discovery made by the astrophysicists Aparicio, Belmonte and Esteban, from the Instituto de Astrofísica de Canarias that the "pyramids" were astronomically oriented and being convinced that they were of ancient origin, he claimed that the ancient people who built them were most likely sun worshipers. Heyerdahl advanced a theory according to which the Canaries had been bases of ancient shipping between America and the Mediterranean.
In subsequent years, Heyerdahl was involved with many other expeditions and archaeological projects. He remained best known for his boat-building, and for his emphasis on cultural diffusionism. He died, aged 87, from a brain tumor. After receiving the diagnosis he prepared for dying by refusing to eat or take medication. The Norwegian government granted Heyerdahl the honor of a state funeral in the Oslo Cathedral on April 26, 2002. His cremated remains lie in the garden of his family's home in Colla Micheri.

- Heyerdahl's expeditions were spectacular and caught the public imagination. Although much of his work remains unaccepted within the scientific community, Heyerdahl increased public interest in ancient history and anthropology. He also showed that long distance ocean voyages were possible with ancient designs. As such, he was a major practitioner of experimental archaeology. He introduced readers of all ages to the fields of archaeology and ethnology.
