Zur Geschichte der Geophysik

Alfred Wegener's most important work, the theory of continental drift, has a key position in the history of geophysics and has crucially advanced the discussion of this central problem of geodynamics amongst supporters and adversaries. The aim of this paper is to paint a portrait of Wegener's personality, of his stations of life, and of his interests and research work. The conceptions of the origin of continents and oceans prior to Wegener, and the further development of his ideas after his death on the ice cup of Greenland 50 years ago are discussed.
