Study Notes
Alfred Wegener: Continental Drift Theorist
- Wegener, a meteorologist and Arctic explorer, proposed the theory of continental drift
- Despite not being a geologist, he gathered evidence from various research areas
- His ideas weren't accepted until after his death, a common fate for groundbreaking innovators
- Born in Berlin, Germany, the youngest of five children
- Earned a PhD in astronomy at Berlin University, then shifted to meteorology
- Worked at a meteorological station in Beeskow, with his brother Kurt, pioneering weather balloon use to study air movement
- In 1906, led a Greenland expedition, building the first meteorological station there
- His Greenland experience led him to question why continents fit together
- Noticed matching coastlines of continents
- In 1930, Wegener's fourth Greenland expedition ended tragically. He died at age 50.
- His fourth expedition, to Greenland in 1930, was planned for his 50th birthday, but it was cut short, never returning.
- The expedition was completed by his brother.
Wegener's Career and Impact
- Drafted into the German army during World War I; released in 1914 after being wounded.
- Published "The Origin of Continents and Oceans" in 1915, including maps illustrating continental drift
- Later, became a professor of meteorology and geophysics at Graz University, Austria in 1924
- Discovered fossil evidence in 1911 that linked Africa and South America before they drifted apart
- Published his continental drift theory in two 1912 papers that explained continental drift in a series of lectures.
