Peter Jakubowski (1947- ) was born in Poland and after attaining a doctoral degree in physics he moved to Germany in 1985. His principal area of interest ‘is a complete refoundation of physics and its practical applications in modern industry’. His ideas are explained in his book, Naturics  and his website(a).
Jakubowski had devoted space on his website to air his thoughts regarding Atlantis but later removed them during a 2011 revamp of the site. He appears to closely follow the views of Axel Hausmann(c). He located Atlantis on Sicily and the Malta Plateau and explained that the circular features of the capital city were in fact the remnants of an asteroid impact crater.
Stelios Pavlou has noted that “In 2001, Jakubowski published Atlantis of the Neanderthals, in which he argues that Atlantis was a Neanderthal civilization that was destroyed in 4804 BC. After that, civilizations of [modern] man ruled. He also argues that all of humanity descended from Atlantis. It is unclear whether he means this in a spiritual, scientific, or physical sense. Jakubowski further claims that the people of Atlantis were [up to] about five or six meters tall.
The most recent revised edition of his book is dated February 2014 and draws extensively on the work of Colin Wilson. Jakubowski formerly supported the notion of Atlantis in Sicily and Malta. It is unclear if this is still the case as all mentions of Sicily and Malta were removed in the book’s recent revision.”(d)
>In 2014, coincidentally shortly after Wilson died, Jakubowski revised and expanded the 2001 paper into an ebook, Atlantis of the Neanderthals  with the subtitle of Colin Wilson Corrected. The book, available online(e), offers a review of Wilson’s Atlantis and the Kingdom of the Neanderthals . However, the purpose of the book seems to be to promote Jakubowski’s theories of ‘unified physics’ (naturics) rather than to criticise Wilson’s ideas.<
In 2016, Jakubowski sent an open letter(b) to Graham Hancock following the publication of Magicians of the Gods. In this somewhat rambling missive, he touches on the Younger Dryas, ancient giants and the evolution of human civilisation.
