Alfred Wegner and Continental Drift

Initial Observation

Alfred Wegener first noticed the striking fit between South America and Africa on Christmas Day, 1910. While examining a world atlas at a friend's house, he observed that the continents seemed to fit together like puzzle pieces. This idea wasn't entirely new, as decent maps published since the 16th century had led others to similar conclusions. However, Wegener took it further by cutting out maps and piecing the landmasses together 1.

He made the observation that South America and Africa seemed like they fit together like pieces in a puzzle.

Wegener's curiosity and methodical approach set the stage for his revolutionary theory of Continental Drift.

   

Pre-Wegener Contributors

Before Wegener, several key figures had noticed the continental fit. Dutch cartographer Abraham Ortelius was likely the first to suggest that the Americas were torn away from Europe and Africa by earthquakes and floods. Other scientists like Theodore Christoph Lilienthal, Alexander von Humboldt, and Antonio Snyder Pellegrini also made similar observations. Despite these early insights, it was Wegener who synthesized these ideas into a coherent theory 1.

Ortelius created the first modern atlas in 1570, which means he was probably the first person to have the idea.

Wegener's work built upon these earlier contributions, leading to a paradigm shift in geology.
