Alfred Wegener (November 1, 1880–November 1930) was a German meteorologist and geophysicist who developed the first theory of continental drift and formulated the idea that a supercontinent known as Pangaea existed on the Earth millions of years ago. His ideas were largely ignored at the time they were developed, but today they are widely accepted by the scientific community. As part of his research, Wegener also took part in several journeys to Greenland, where he studied the atmosphere and ice conditions.

Early Life

Alfred Lothar Wegener was born on November 1, 1880, in Berlin, Germany. During his childhood, Wegener's father ran an orphanage. Wegener took an interest in physical and earth sciences and studied these subjects at universities in both Germany and Austria. He graduated with a Ph.D. in astronomy from the University of Berlin in 1905. He briefly served as an assistant at the Urania Observatory in Berlin.

While earning his Ph.D. in astronomy, Wegener also took an interest in meteorology and paleoclimatology (the study of changes in the Earth's climate throughout its history). From 1906 to 1908 he went on an expedition to Greenland to study polar weather. In Greenland, Wegener established a research station where he could take meteorological measurements. This expedition was the first of four dangerous trips that Wegener would take to the icy island. The others occurred from 1912 to 1913 and in 1929 and 1930.

Continental Drift

Shortly after receiving his Ph.D., Wegener began teaching at the University of Marburg in Germany, and in 1910 he drafted his "Thermodynamics of the Atmosphere," which would later become an important meteorological textbook. During his time at the university, Wegener developed an interest in the ancient history of the Earth's continents and their placement. He had noticed, in 1910, that the eastern coast of South America and the northwestern coast of Africa looked as if they were once connected. In 1911, Wegener also came across several scientific documents stating there were identical fossils of plants and animals on each of these continents. He eventually articulated the idea that all of the Earth's continents were at one time connected into one large supercontinent. In 1912, he presented the idea of "continental displacement"—which would later become known as "continental drift"—to explain how the continents moved toward and away from one another throughout the Earth's history.

In 1914, Wegener was drafted into the German Army during World War I. He was wounded twice and was eventually placed in the Army's weather forecasting service for the duration of the war. In 1915, Wegener published his most famous work, "The Origin of Continents and Oceans," as an extension of his 1912 lecture. In that work, he presented extensive evidence to support his claim that all of the Earth's continents were at one time connected. Despite the evidence, however, most of the scientific community ignored his ideas at the time.

Later Life

From 1924 to 1930, Wegener was a professor of meteorology and geophysics at the University of Graz in Austria. At a 1927 symposium, he introduced the idea of Pangaea, a Greek term meaning "all lands," to describe the supercontinent that he believed existed on the Earth millions of years ago. Scientists now believe that such a continent did exist—it probably formed about 335 million years ago and began to split apart 175 million years ago. The strongest evidence of this is—as Wegener suspected—the distribution of similar fossils throughout continental borders that are now many miles apart.


In 1930, Wegener took part in his last expedition to Greenland to set up a winter weather station that would monitor the jet stream in the upper atmosphere over the North Pole. Severe weather delayed the start of the trip and made it extremely difficult for Wegener and the 14 other explorers and scientists with him to reach the weather station. Eventually, 12 of these men would turn around and return to the group's base camp near the coast. Wegener and two others continued on, reaching the final destination of Eismitte (Mid-Ice, a site near the center of Greenland) five weeks after the start of the expedition. On the return trip to the base camp, Wegener became lost and is believed to have died sometime in November 1930 at the age of 50.


For most of his life, Wegener remained dedicated to his theory of continental drift and Pangaea despite receiving harsh criticism from other scientists, many of whom believed the oceanic crust was too rigid to permit the movement of tectonic plates. By the time of his death in 1930, his ideas were almost entirely rejected by the scientific community. It was not until the 1960s that they gained credibility as scientists began studying seafloor spreading and plate tectonics. Wegener's ideas served as a framework for those studies, which produced evidence that supported his theories. The development of the Global Positioning System (GPS) in 1978 eliminated any residual doubt there may have been by providing direct evidence of continental movements.

Today, Wegener's ideas are highly regarded by the scientific community as an early attempt at explaining why the Earth's landscape is the way it is. His polar expeditions are also highly admired and today the Alfred Wegener Institute for Polar and Marine Research is known for its high-quality research in the Arctic and the Antarctic. A crater on the Moon and a crater on Mars are both named in Wegener's honor.
