Alfred Wegener was a German meteorologist who, in 1912, advocated the theory of continental drift, arguing that the continents on either side of the Atlantic Ocean were drifting apart.
In 1915, Wegener published the theory that there had once been a giant supercontinent, called Pangaea, which broke up and drifted apart ~200 million years ago.
Most geologists ridiculed Wegener for his ideas. In the 1950s and 60s, Bruce Heezen, Harry Hess, and Robert Dietz concluded that the seafloor was spreading and argued that this caused continental drift.
