The name of Immanuel Velikovsky, one can say with confidence, is practically unknown to the average Russian reader; it cannot be found in our recent encyclopedias either. This remarkable man, a doctor by training and a scientist by vocation, devoted four decades of his life to science - astronomy, geology, paleontology, history, psychoanalysis. The result of his many years of hard work was a series of scientific works on ancient history - “Worlds in Collisions”, “Centuries in Chaos”, “Ramses II and His Time”, “Peoples of the Sea”, etc. The book tells about the difficult life and creative path of this interesting a person - a doctor, scientist, writer - a native of the Russian Empire.
