Wegener, Alfred Lothar
German meteorologist and geophysicist whose theory of continental drift, expounded in Origin of Continents and Oceans in 1915, was originally known as ‘Wegener's hypothesis’. His ideas can now be explained in terms of plate tectonics, the idea that the Earth's crust consists of a number of plates, all moving with respect to one another.
