Abstract Alfred Wegener was an accomplished German natural scientist in the fields of meteorology, astronomy, and geology. He was also a skilled balloonist and participated in three scientific expeditions to Greenland. His primary research interest was in the relatively new field of meteorology. He held several academic or research positions in Germany before taking the Chair of meteorology and geophysics at the University of Graz in Austria in 1924. Wegener's most notable scientific contribution was a unified theory for the origin of continents. His mobilist idea of drifting continents contrasted sharply with the contemporary view of fixed continents and a rigid, shrinking Earth. Wegener first presented his theory of continental drift in 1912 at a meeting of the German Geological Association. In 1915, he published his evidence and conclusions in a now-classic book, Die entstehung der kontinente und ozeane (The origin of continents and oceans). Wegener proposed that all
