His books were controversial

Erich von Däniken made a name for himself worldwide as a controversial researcher of the gods. His books have sold millions of copies. Erich von Däniken was born on April 14, 1935 in Zofingen in the canton of Aargau and grew up in a strict Catholic family in Schaffhausen.

As a pupil at a Jesuit boarding school in Fribourg, he learned ancient languages. He questioned much of what he read in Latin and Greek lessons in translations from the Old Testament.

With "Memories of the Future" in 1968, von Däniken triggered a science fiction boom and conquered the bestseller lists. With his interpretations of ancient lore, the then hotelier celebrated worldwide success as an amateur researcher. The "New York Times" even wrote of an outbreak of "Dänikenitis".

His first book was followed by numerous other books, documentaries and television series. The hobby researcher von Däniken became an entrepreneur and later set up a foundation.

Managers described him as charismatic and inspiring

Von Däniken's manager Ramon Zürcher described him as charismatic, enthusiastic and always curious - qualities that carried him through life.

And a generous host, they had all visited him: astronauts, cosmonauts, scientists.

He cultivated a friendship with Professor Harry Ruppe, for example, a long-time colleague of Wernher von Braun. Von Braun was the famous rocket builder from Nazi Germany who later moved to the USA and worked for NASA for a long time.

No luck at the Mystery Park in Interlaken

With his mixture of pseudo-science and entertainment, von Däniken reaches an audience of millions. He is ridiculed and revered. In 1973, "Der Spiegel" wrote of the "Däniken hoax", of delusion and business, but also of a "world phenomenon".

Either way, von Däniken struck a chord with the times, somewhere between conspiracy theory and recognized science.

In 1995, von Däniken and his wife moved to Beatenberg in the Bernese Oberland. He moved into an office in Unterseen near Interlaken BE, which became an archive - with thousands of books, relics and documents. All proof of his theories.

However, his theme park in Interlaken had to close in November 2006 after two and a half years due to financial problems. Von Däniken, who was otherwise so spoiled by success, had no luck with the Mystery Park.

No UFO sightings

In 2009, von Däniken began to work as a diligent Twitterer (now X). He also entertained a large audience there. Sometimes pointed, sometimes below the belt, often irrelevant, often about climate change.

Von Däniken advocated the theory that extraterrestrials visited the earth in prehistoric times and influenced human civilization - but he never saw one himself.
