Photo from the back of the book dust cover. The caption reads: "Hugh Auchincloss Brown holds the "Doomsday Toy," illustrating his theory of the shift in the earth's axis, which is precipitated by the interaction of a polar ice-cap with the force of gravity".
Hugh Auchincloss Brown (23 December 1879 – 19 November 1975) was an electrical engineer best known for advancing a theory of catastropic pole shift. Brown claimed that massive accumulation of ice at the geographical pole caused recurring tipping of the axis in cycles of approximately 4000-7500 years. Brown argued that because the earth wobbles on the axis and the crust slides on the mantle, a shift was demonstrably imminent, and suggested the use of nuclear explosions to break-up the ice to forestall catastrophe.
