who wrote the book the earths shifting crust
Charles Hapgood In 1958, Hapgood published The Earth's Shifting Crust which denied the existence of continental drift and featured a foreword by Albert Einstein. In Maps of the Ancient Sea Kings (1966) and The Path of the Pole (1970), Hapgood proposed the hypothesis that the Earth's axis has shifted numerous times during geological history.[2] The Path of the Pole was meant as a replacement for The Earth's Shifting Crust after corrections were suggested to him. Hapgood writes in Voices of Spirit (1975): "In later discussions we discussed the theories of my book ‘Earth’s Shifting Crust’, and he [Einstein] suggested that one of them was wrong; as a result of this I revised my book, which subsequently was republished as ‘The Path of the Pole’. My own further research confirmed the truth of his observation, which involved technicalities of geophysics.”
