Alfred Wegener biography
Alfred Wegener, (full name Alfred Lothar Wegener), was born in Berlin on November 1, 1880.
He gained a doctoral degree in Astronomy from the University of Berlin in 1904.
Plate Tectonics - Continental Drift
After 1906 Alfred Wegener participated in several expeditions to Greenland where high altitude air masses were
tracked and where the existence of so-called "jet streams" of air at high altitude became scientifically established.
Alfred Wegener actually met his end on one of these expeditions to Greenland.
expedition had been intended to take readings of the arctic weather in Greenland during the course of a year. Wegener
led a party to re-provision a forward camp,
known as Eismitte, (or Mid-Ice), deep the interior which was running out of fuel
and and had not already been re-supplied due to a late and limited summer thaw that year.
The party set out in late september, 1930, and suffered terribly in temperatures
of -60o C
in replenishing the forward camp's stores. Only Wegener and two others actually made it through with twelve
others from the original party returning to a base camp. The journey from the base camp to the forward camp
having taken all of four weeks to complete.
The stores Wegener had helped to bring were, however, very limited and he and one other person volunteered to
leave the forward camp with its replenished fuel and foodstuffs just taking with them enough stores to reach
the safety of the base camp. It was by now well into October and winter was closing in again - they even seem to
have intended that their sled-dogs would have to survive by consuming their
weaker comrades who were to be sacrificed in order to keep the stronger ones alive.
Neither Alfred Wegener, nor his comrade on this perilous journey, Rasmus Villumsen, reached the base camp
alive. Wegener at the presumed time of his death (early November 1930), was fifty years of age and had been a
notably heavy smoker.
His body was recovered in May, 1931 - that of Rasmus Villumsen has never been found.
Continental Drift and Plate Tectonics
From circa 1911 Alfred Wegener, after being influenced by a scientific paper he had come across
that listed fossils of identical plants and animals found on opposite sides of the Atlantic,
began proposing a then most controversial theory which held that the continents
of the earth had once been joined together but had drifted apart through a process that he
explicitly, by circa 1915 - with the publication of the first edition of The Origin of Continents and Oceans, a book outlining
Wegener's theory, - seems to have referred to as Continental Drift
(actually - in his own mother tongue - as Kontinentalverschiebung or die Verschiebung der Kontinente).
As he later wrote: "A conviction of the fundamental soundness of the idea took root in my mind."
It was only in the early 1950s with the emergence of the new science of Paleomagnetism that Alfred Wegener's
of Continental Drift
began to be taken anything like seriously by mainstream geologists and other scientists culminating in an
acceptance by mainstream science of a revised Theory of Plate Tectonics in the 1960s.
Another momentous theory
The Wisdoms and Insights available on our
site include some about Human Existence itself:-
"...man is a bundle of relations, a knot of roots,
whose flower and fruitage is the world..."
Ralph Waldo Emerson
It seems highly likely that such Human-innate
"bundles of relations and knots of roots"
give rise to the "World" of Human Societies!!!
