Alfred Wegener

Alfred Wegener proposed "continental drift" theory in 1912 and developed it extensively for nearly twenty years. His book on the subject, "The Origin of Continents and Oceans", went through four editions and was the focus of an international controversy in his lifetime and for some years after his death.

Wegener's basic idea was that many problems and puzzles of the earth's history could be solved if one supposed that the continents moved laterally rather than supposing that they remained fixed in place. Wegener worked over many years to show how such continental movements were plausible and how they worked, using evidence and results from geology, geodesy, geophysics, paleontology, climatology and paleogeography.

Although he was the author of a "geological theory", he was not a geologist. He was trained as an astronomer and pursued a career in atmospheric physics. When he proposed the theory of continental displacements (1912), he was 31 years old and an instructor of physics and astronomy at the University of Marburg, Germany. In 1906, he and his brother had set a world record for time aloft in a free balloon : fifty-two hours. Between 1906 - 1908 he had taken part in a highly publicized expedition to explore the coast of northeast Greenland. He was also known to the circle of meteorologists and atmospheric physicists in Germany as the author of a textbook, "Thermodynamics of the Atmosphere" (1911). He also wrote a number scientific papers on atmospheric layering.

Early life

Born in 1843, Richard Wegener was ninth of the eleven children of Friedrich Wilhelm Wegener, an owner of a military uniform factory in Wittstock, in the northwest corner of Brandenburg, about 90 kilometers from Berlin. Richard realized his father's ambition to study theology and become an evangelican clergymen. After his seminary study and ordination in 1868, he spent a year as an assistant pastor to parish in Kolmar, Posen -- the Prussian province centered on the historic Polish city of Poznan. Carefully saving his annual salary and his Christmas bonus, he returned to Wittstock and asked Anna Schwarz to marry him. Anna was herself an orphan, born in the tiny hamlet of Zechlinerhutte and raised by relatives in nearby Wittstock. She and Richard had met as students.

For the next five years, Richard supported himself and his wife on the salary of an assistant pastor. Richard studied Greek, Latin and Hebrew and earned a PhD from the Friedrich-Wilhelms University in Berlin in 1873. In that same year, Richard and Anna took over the Schindler Orphanage. Richard began his parallel career teaching Greek and Latin at the Gymnasium zum Grauen Kloster, the illustrious secondary school that the older orphans attended along with the children of Berlin's cultural elite. Richard also fed his other interest and commitments by teaching German literature at a nearby Mädchenschule (girl's school) and holding a chaplaincy at the criminal court in the nearby neighborhood of Moabit.

Later, Alfred Lothar Wegener was born in Berlin, 1 November 1880. Alfred was the fifth and youngest child of Richard Wegener and Anna Schwarz. His birthplace was a converted Austrian embassy at 57 Friedrichsgracht, a scant few blocks from the Imperial Palace, facing the Spree Canal, on the southeastern side of the island. This structure was home to Schindler Orphanage. The spacious interior of the building was more than adequate to house the Wegener family, the thirty or so orphans in their charge, Richard Wegener's assistants in the teaching and daily supervision of the orphans, and the resident domestics under the direction of Anna Wegener.

By the time Alfred was born in 1880, Tony (seven) and Willi (six) were already in school. Alfred spent the day with Kurt and his sister Käte, supervised by Anna and the resident domestics. In 1884, when Alfred Wegener was not quite four years old, his sister Käte died quite suddenly after a brief illness. Alfred's mother said that it was likely the close spacing of her last three children (1878, 1879, 1880) that had rendered them less vigorous than the older Tony and Willi, born earlier in the marriage. Moreover, the metropolitan air had left the younger ones "pale and listless". Industrial growth in the last few decades of the 19th century brought great chemical works, paper mills, machine shops, textile and carpet factories to Berlin and its burgeoning suburbs. Much of this development occured just to the north and east of the Museum Insel and these factories were largely fueled by lignite, a poor-quality coal that produced huge quantities of fly ash.
