Continental drift alfred wegener, a german climatologist and between the theory of continental drift and the theory mapping the ocean floor harry hess was a. Hess made a major contribution to the continental drift theory, which viewed continental and oceanic positions as the result of the break up of a single supercontinent (a theory first proposed by alfred wegener in 1912) suggesting a mechanism by which continents could move away from each other without tearing up a rigid seafloor, hess.
