Harry Hammond Hess (1906–1969) was an American geologist and a major figure in the development of the theory of plate tectonics. He is best known for his contributions to the understanding of seafloor spreading, a key concept in the theory of plate tectonics which explains how new oceanic crust is formed at mid-ocean ridges and how it subsequently moves away from the ridges, causing continental drift.
