People began to notice that coastlines of continents fit together like puzzle pieces primarily when Alfred Wegener proposed the idea of continental drift in the early 20th century, specifically in 1912. Wegener's hypothesis suggested that the continents were once part of a single landmass, which he called Pangaea, and had drifted apart over geological time. While early explorers and geologists may have noted similarities, it was Wegener's work that explicitly connected the shapes of the continents to the concept of continental movement.
