[Theory of Continental Drift: Five Landmark First Editions]
FIVE FIRST EDITIONS DOCUMENTING THE INTRODUCTION AND DEVELOPMENT OF WEGENER'S THEORY OF CONTINENTAL DRIFTIf we are to believe in Wegener’s hypothesis we must forget everything which has been learned in the last 70 years and start all over again –Alexander du Toit, Our Wandering Continents (1937).From the mid-1920s to the mid-1960s most geologists worked within Permanentist or Contractionist frameworks. Few adhered to Drift. From the mid-1950s, two developments took place. First, some groups of geologists concentrated on new phenomena and geophysical data which had come to light since Wegener. Second, new versions of Drift were put forward... By the early 1970s the ‘modern revolution’ in geology was complete: the plate tectonics version of Drift, in which the surface of the earth was composed of slowly-moving slabs of crust, was firmly entrenched as the new orthodoxy. –Homer Eugene LeGrand, Drifting Continents and Shifting Theories Wegener, Alfred.
