Alfred Wegener:

Alfred Wegener was a very great man who didn't know much about the world, until he was injured during WWI. While Wegener was recuperating, he had all the time in the world to think about the coast lines of South America and Africa, and how fossils of the same type were found on both continents. Unlike others before him, Wegener decided that he would find evidence to support a theory that the continents used to be connected. While he was looking at a world map he began to think that the continents looked like they could fit together like a big jigsaw puzzle. When he had fitted the continents together, he decided to call this landmass Pangaea (pan-Jee-uh) meaning "all lands". Since he thought of Pangaea, he also believed that the oceans were once connected, and named it Panthalassa meaning "all seas". Wegener also believed that around 200 million years ago, Pangaea began to break up and he thought that this motion, Continental Drift, crumpled the crust in places creating mountain's, such as the Andes, Himalayas, and Rockies.
