Josef F. Blumrich (1913-2002), aeronautical and aerospace engineer and author, is best known in technical circles for his work at NASA, where he was involved in development of the Saturn V rockets that were used to launch the Apollo spacecraft used for the moon landings, as well as Skylab, the United States orbiting space station
that was the forerunner of the International Space Station.
Blumrich is best known to the general public for his research into paleo-SETI, the "ancient astronauts as gods" theory first popularized by Swiss author Erich von Däniken which conjectures that alien astronauts from outside our solar system visited ancient cultures such as the Egyptians, Mayans, Incas, Tibetans, and others and that, not recognizing advanced, technology, people meeting or seeing these visitors thought them to be gods.
Blumrich is unique among paleo-SETI authors in that he is the only author writing about "ancient astronauts as gods" who is an acknowledged expert in aerospace design and engineering with solid professional credentials including a string of patents, professional engineering society memberships, serving as a peer reviewer for professional technical journals, and authoring a number of articles published in peer-reviewed technical journals.
Josef Blumrich's most widely known work is his book The Spaceships of Ezekiel, which has been translated into numerous languages.
