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.
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.
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.
Hess possessed two valuable skills: careful attention to detail and the ability to form sweeping hypotheses. This unusual combination produced groundbreaking work on a number of subjects, including the origin of ocean basins and island arcs, mountain building, and the movement of continents.
Harry Hammond Hess. 1906-1969. American Geologist. Born in New York in 1906, Harry Hammond Hess was considered a "very promising student" even in his high school years.
The man typically credited with revealing this now generally accepted scientific theory was Harry Hammond Hess, a geologist, and officer in the United States Navy during World War II. The theory of continental drift had been proposed before Hess’ time, perhaps as early as 1907 by various scientists and researchers.
…early 1960s, the American geophysicist Harry H. Hess proposed that new oceanic crust is continually generated by igneous activity at the crests of oceanic ridges—submarine mountains that follow a sinuous course of about 65,000 km (40,000 miles) along the bottom of the major ocean basins.
