Harry Hammond Hess (May 24, 1906 – August 25, 1969) was an American geologist and a United States Navy officer in World War II who is considered one of the "founding fathers" of the unifying theory of plate tectonics.
Harry Hess published 'The History of Ocean Basins' in 1962, outlining a theory of how tectonic plates can move which was later called 'sea floor spreading'. He identified the presence of mid ocean ridges, and that ocean trenches are where ocean floor is destroyed and recycled.
This led to his discovery of submerged and curiously flat-topped mountains that he named “guyots” in honor of the Swiss founder of the Princeton geology department. It also produced thousands of miles of echo-sounding surveys of the ocean floor.
1 Οκτ 2024 · In this paper, Hess, drawing on Holmes’s model of convective flow in the mantle, suggested that the oceanic ridges were the surface expressions of rising and diverging convective mantle flow, while trenches and Wadati-Benioff zones, with their associated island arcs, marked descending limbs.
It happened that the command of one attack transport ship, the USS Cape Johnson, was given to Harry Hammond Hess, a geologist from Princeton University. Hess, then in his late thirties, wanted to continue his scientific investigations even while at war.
Harry Hammond Hess. 1906-1969. American Geologist. B orn in New York in 1906, Harry Hammond Hess was considered a "very promising student" even in his high school years. He had no difficulty gaining acceptance into the electrical engineering major group at Yale University in New Haven, Connecticut.
23 Μαΐ 2018 · Hess, Harry Hammond (1906–69) An American geophysicist from Princeton University, Hess made important contributions to the theory of plate tectonics. He devised the concept of sea-floor spreading (see also DIETZ, ROBERT SINCLAIR), and discovered and named guyots.
