Robert Charroux was the best-known pen-name of Robert Grugeau (April 7, 1909 - June 24, 1978).

Robert Charroux worked for the French post office until becoming a full-time writer of fiction in the early 1940s. He also wrote the scripts for a French comic strip, Atomas, about an atomic-powered superhero, appearing in the weekly magazine Mon Journal in the late 1940s. For the same magazine Charroux wrote a science fiction adventure in serial form, "Prof. Barthelemy's Flying Island."

Charroux was a pioneer of the theory of ancient astronauts, publishing at least six non-fiction works in this genre in the last decade of his life, including One Hundred Thousand Years of Man's Unknown History (1963, 1970), Forgotten Worlds (1973), Masters of the World (1974), The Gods Unknown (1974) and Legacy of the Gods (1974).

The influence that Charroux's first work (in its 1963 version) had on Erich Von Däniken's first books (ca. 1966), as well as the influence that Von Däniken's early books had on Charroux, is widely appreciated, but Von Däniken seems to have been equally familiar with an earlier French work, The Morning of the Magicians by Louis Pauwels and Jacques Bergier (1960), which is likely to have been a direct inspiration for both Charroux and Von Däniken.[1] Charroux's publisher contacted Von Däniken's in March 1968 concerning evidence of plagiarism, with the result that later printings of Chariots of the Gods and Return to the Stars at least mentioned Charroux in the bibliography.

Serge Hutin (1927 - 1997) born in France, was an author on books on esoterica and the occult.

Hutin was a writer of many books on the occult and esoteric, he wrote about Freemasonry, secret societies, Rosicrucianism, alchemy and astrology and many other occult topics. Hutin wrote about the Kabbalah and claimed that Isaac Newton was a Christian Kabbalist.

Hutin is most well known in UFO circles for his ancient astronaut book called Alien Races and Fantastic Civilizations (1975) in we he claimed ancient civilizations across the earth were colonial outposts built by extraterrestrials. The book was similar to books by other authors of the time such as Jacques Bergier and Jean Sendy.Hutin also wrote about Atlantis and gave a lot of credit to Plato for writing about it.

Hutin published over 40 books (The following are ones which have been translated into English):

Erich Anton Paul von Däniken (/ˈɛrɨk vɒn ˈdænɨkɨn/; born 14 April 1935 in Zofingen, Aargau) is a Swiss author best known for his controversial claims about extraterrestrial influences on early human culture, in books such as Chariots of the Gods?, published in 1968. Däniken is one of the main figures responsible for popularizing the "paleo-contact" and ancient astronaut hypotheses.

Däniken is a co-founder of the Archaeology, Astronautics and SETI Research Association (AAS RA), and designed the theme park Mystery Park in Interlaken, Switzerland, that first opened on 23 May 2003. Däniken's first book, Chariots of the Gods?, was an immediate best seller in the United States, Europe and India, with subsequent books "according to von Däniken, have been translated into 32 languages and together have sold more than 63 million copies."

His ideas are largely rejected by scientists and academics, who categorize his work as pseudohistory and pseudoarchaeology.

Von Däniken was raised a strict Catholic, and attended the international Catholic school Saint-Michel 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 the phenomenon of flying saucers.

David Vaughan Icke (pronounced /aɪk/, or IKE, born 29 April 1952) is an English writer and public speaker, best known for his views on what he calls "who and what is really controlling the world." Describing himself as the most controversial speaker in the world, he is the author of 19 books and has attracted a global following that cuts across the political spectrum. His 533-page The Biggest Secret (1999) has been called "the Rosetta Stone for conspiracy junkies."

Icke was a well-known BBC television sports presenter and spokesman for the Green Party, when in 1990 a psychic told him he was a healer who had been placed on Earth for a purpose, and that the spirit world was going to pass messages to him so he could educate others. In March 1991 he held a press conference to announce that he was a "Son of the Godhead" – a phrase he said later the media had misunderstood – and the following month told the BBC's Terry Wogan show that the world would soon be devastated by tidal waves and earthquakes. He said the show changed his life, turning him from a respected household name into someone who was laughed at whenever he appeared in public.

Friedrich Wilhelm Nietzsche ( /ˈniːtʃə/;German pronunciation: [ˈfʁiːdʁɪç ˈvɪlhɛlm ˈniːtsʃə]; October 15, 1844 – August 25, 1900) was a German philosopher, poet, cultural critic and classical philologist. He wrote critical texts on religion, morality, contemporary culture, philosophy and science, displaying a fondness for metaphor, irony and aphorism.

Nietzsche's influence remains substantial within and beyond philosophy, notably in existentialism, nihilism and postmodernism. His style and radical questioning of the value and objectivity of truth have resulted in much commentary and interpretation, mostly in the continental tradition. His key ideas include the death of God, the Übermensch, the eternal recurrence, the Apollonian and Dionysian dichotomy, perspectivism and the will to power. Central to his philosophy is the idea of "life-affirmation", which involves an honest questioning of all doctrines that drain life's expansive energies, however socially prevalent and radical those views might be.
