Erich Anton Paul von Däniken (; ; 14 April 1935 – 10 January 2026) was a Swiss author of several pseudoscientific books which made claims about extraterrestrial influences on early human culture, including the best-selling Chariots of the Gods?, published in 1968. Däniken was one of the main figures responsible for popularizing the "paleo-contact" and ancient astronauts hypotheses.
The ideas put forth in his books are rejected by virtually all scientists and academics, who categorize his work as pseudohistory, pseudoarchaeology, and pseudoscience. Early in his career, he was convicted and served time for several counts of fraud or embezzlement, and wrote one of his books in prison.
Däniken was the co-founder of the Archaeology, Astronautics and SETI Research Association (AAS RA). He designed Mystery Park, a theme park located in Interlaken, Switzerland, that opened in May 2003.
Early life Däniken was born in Zofingen, Aargau. Brought up as a Roman Catholic, he attended the Saint-Michel International Catholic School in Fribourg, Switzerland. During his time at the school he rejected the church's interpretations of the Bible and developed an interest in astronomy and flying saucers. At the age of 19, he was given a four-month suspended sentence for theft. He left the school and was apprenticed to a Swiss hotelier for a time,Story(1976), p. 1 before moving to Egypt. In December 1964, Däniken wrote ("Were Our Ancestors Visited by Extraterrestrials?" [lit. "Did our ancestors have visitation from space?"]) for the German-Canadian periodical .Peter Krassa, Disciple of the Gods: A Biography of Erich von Däniken (W. H. Allen & Co., Ltd, 1976, ), p. 74 While in Egypt, he was involved in a jewelry deal which resulted in a nine-month conviction for fraud and embezzlement upon his return to Switzerland.
Following his release, Däniken became a manager of the Hotel Rosenhügel in Davos, Switzerland, during which time he wrote Chariots of the Gods? (, literally "Memories of the Future"), working on the manuscript late at night after the hotel's guests had retired. The draft of the book was turned down by several publishers. Econ Verlag (now part of Ullstein Verlag) was willing to publish the book after a complete reworking by a professional author, Utz Utermann, who used the pseudonym of Wilhelm Roggersdorf. Utermann was a former editor of the Nazi Party's newspaper and had been a Nazi bestselling author."Wilhelm Utermann" (in German), Lexikon westfälischer Autorinnen und Autoren. The re-write of Chariots of the Gods? was accepted for publication early in 1967, but not printed until March 1968. Against all expectations, the book gained widespread interest and became a bestseller. Däniken was paid 7 percent of the book's turnover, while 3 percent went to Utermann.Gerhard Mauz (9 February 1970), , 5202660, no. 7, p. 98 In 1970, referred to the hype over Däniken as Dänikitis., 44418148, no. 40, 28 September 1970, p. 214
In November 1968, Däniken was arrested for fraud, after falsifying hotel records and credit references in order to take out loans for $130,000 over a period of twelve years. He used the money for foreign travel to research his book. Two years later, Däniken was convicted for "repeated and sustained" embezzlement, fraud, and forgery, with the court ruling that the writer had been living a "playboy" lifestyle. He unsuccessfully entered a plea of nullity, on the grounds that his intentions were not malicious and that the credit institutions were at fault for failing adequately to research his references, and on 13 February 1970 he was sentenced to three and a half years imprisonment and was also fined 3,000 francs.Von Däniken's side of the story is given in Krassa, pp. 96–107. He served one year of this sentence before being released.Transcripts of Däniken's letters to his wife Elizabeth (whom he married in 1959), during this period are provided in Krassa, pp. 130–135.
His first book, Chariots of the Gods?, had been published by the time of his trial, and its sales allowed him to repay his debts and leave the hotel business. Däniken wrote his second book, Gods from Outer Space, while in prison.
Claims of alien influence on Earth The general claim of Däniken over several published books, starting with Chariots of the Gods? in 1968, is that extraterrestrials or "ancient astronauts" visited Earth and influenced early human culture. Däniken wrote about his belief that structures such as the Egyptian pyramids, Stonehenge, and the Moai of Easter Island, and certain artifacts from that period, are products of higher technological knowledge than is presumed to have existed at the times they were manufactured. He also describes ancient artwork throughout the world as containing depictions of astronauts, air and space vehicles, extraterrestrials, and complex technology. Däniken explains the origins of religions as reactions to contact with an alien race, and offers interpretations of sections of the Old Testament of the Bible.
Criticism In 1966, when Däniken was writing his first book, scientists Carl Sagan and I. S. Shklovskii had written about the possibility of paleocontact and extraterrestrial visitation claims in one chapter of their book Intelligent Life in the Universe, leading author Ronald Story to speculate in his book The Space Gods Revealed that this may have been the genesis of Däniken's ideas. Many ideas from this book appeared in different form in Däniken's books.
Prior to Däniken's work, other authors had presented ideas of extraterrestrial contacts. He failed to credit these authors properly or at all, even when making the same claims using similar or identical evidence. The first edition of Däniken's Erinnerungen an die Zukunft failed to cite Robert Charroux's One Hundred Thousand Years of Man's Unknown History despite making very similar claims, and publisher Econ-Verlag was forced to add Charroux in the bibliography in later editions, to avoid a possible lawsuit for plagiarism.
Logical and factual errors
Iron pillar of Delhi
In Chariots of the Gods?, Däniken cited the iron pillar of Delhi in India, erected approximately 402 AD, as a prime example of extraterrestrial influence because of its "unknown origins" and a complete absence of rust despite its estimated 1,500 years of continuous exposure to the elements.Däniken, Erich von: Chariots of the Gods?, p. 94. When informed by an interviewer in 1974 that the origin of the pillar, its method of construction and relative resistance to corrosion were all well understood, Däniken responded that he no longer believed extraterrestrials had been involved in its creation.Playboy, p. 64, Volume 21 Number 8, 1974
Cueva de los Tayos In The Gold of the Gods, Däniken described an expedition he claimed to have undertaken through man-made tunnels within Cueva de los Tayos, a natural cave system in Ecuador, guided by the Hungarian-born Argentine explorer Juan Moricz. He reported seeing mounds of gold, strange statues, and a library containing metal tablets, all of which he considered to be evidence of ancient extraterrestrial visitation.
Moricz told Der Spiegel that there had been no expedition; Däniken's descriptions came from "a long conversation", and the photos in the book had been "fiddled". During the 1974 interview, Däniken asserted that he had indeed seen the library and the artifacts in the tunnels, but he had embellished some aspects of the story to make it more interesting:
Four years later, he admitted that he had never been inside Cueva de los Tayos, and had fabricated the entire cave adventure. A geologist found no evidence of artificial tunnels in the area. Father Crespi's gold artifacts, according to an archeologist consulted by Der Spiegel, were mostly brass imitations sold locally as tourist souvenirs.
Book of Dzyan and "Tulli Papyrus" Samuel Rosenberg said that the Book of Dzyan, referred to by Däniken, was "a fabrication superimposed on a gigantic hoax concocted by Madame Blavatsky." He also says that the "Tulli Papyrus", cited by Däniken in one of his books, is probably cribbed from the Book of Ezekiel, and quoted Nolli (through Walter Ramberg, Scientific Attache at the U.S. Embassy in Rome), then current Director of the Egyptian Section of the Vatican Museum, as "suspect[ing] that Tulli was taken in and that the papyrus is a fake."Edward Uhler Condon, "Scientific Study of Unidentified Objects", Bantam, 1969, cited by the 1974 NYT article "Erich Däniken's genesis" According to Richard R. Lingeman of The New York Times, it is likely that Däniken obtained these references from UFO books that mentioned them as real documents.
Nazca Lines
Däniken brought the Nazca lines to public prominence in Chariots of the Gods? with his proposal that the lines were built on instructions from extraterrestrial beings as airfields for their spaceships. In his 1998 book Arrival of The Gods, he added that some of the pictures depicted extraterrestrials. The idea did not originate with Däniken; it began after people who first saw the lines from the air made joking comparisons to Martian "canals", and had already been published by others.
Descriptions of some Nazca line photos in Chariots of the Gods? contain significant inaccuracies. One, for example, purporting to demonstrate markings of a modern airport, was actually the knee joint of one of the bird figures, and was quite small. Däniken said that this was an "error" in the first edition, but it has not been corrected in later editions.
Consensus among archeologists is that the Nazca lines were created by pre-Columbian civilizations for cultural purposes. Efforts by archeologists to refute fringe theories such as Däniken's have been minimal, however. Silverman and Proulx have said that this silence from archaeologists has harmed the profession, as well as the Peruvian nation. Däniken's books attracted so many tourists to the Nazca region that researcher Maria Reiche had to spend much of her own time and money preserving the lines.
Piri Reis map
Däniken wrote in Chariots of the Gods? that a version of the Piri Reis map depicted some Antarctic mountains that were and still are buried in ice, and could only be mapped with modern equipment. His theory relies on the book of Maps of the Ancient Sea Kings by Charles Hapgood. A.D. Crown, in Some Trust in Chariots, explains how this is simply wrong. The map in Däniken's book only extends five degrees south of the equator, ending in Cape São Roque, which means that it does not extend to Antarctica. Däniken also said that the map showed some distortions that would only happen if it was an aerial view taken from a spaceship flying above Cairo, but in fact it does not extend far enough to the south to cause visible distortions in an aerial view. Däniken also asserts the existence of a legend saying that a god gave the map to a priest, the god being an extraterrestrial being. But Piri Reis said that he had drawn that map himself using older maps, and the map is consistent with the cartographic knowledge of that time."Report No. 83-205 SPR The UFO Enigma, Marcia S. Smith, 20 June 1983, Congressional Research Service, Appendix B, pp. 127–130, quoting "Some trust in chariots: sixteen views on Erich von Däniken's Chariots of the gods", editors Thiering, Barry and Edgar Castle, West Books, 1972 Also, the map is not "absolutely accurate" as claimed by Däniken, since it contains many errors and omissions;, a fact that Däniken did not correct when he covered the map again in his 1998 book Odyssey of the Gods. Other authors had already published this same idea, a fact that Däniken did not recognize until 1974 in an interview with Playboy magazine.
