100 Years of Drift, Part 1: from meteorology to moving continents
Wegener is not the only scientist for whom meteorology has been the starting point on the path to other major discoveries. It influenced Dalton’s thinking in the development of atomic theory, while writing computer programs for meteorology was Paul Crutzen’s first step towards discovering how CFCs were destroying the ozone layer.
Wegener himself gets a supporting role in the admirable Horrible Science book (reviewed here), Evolve or Die.

Fifty years ago, we finally figured out why the Earth has mountains. But one hundred years ago, Alfred Wegener had already offered an explanation – it took those extra 50 years for his grand idea to catch on. The continents, Wegener said, wander about. They bump into each other. Accidents cause mountains.
Yea, it’s been a hundred years since Wegener first wrote about continental displacement. A few other people had similar notions earlier. In the 1600s, Francis Bacon speculated that the southern hemisphere’s continents were arranged “like an opening blossom.” Some say Bacon was wondering if they had drifted from an original supercontinent, though Bacon never really said that.
In the 1800s, a few notable geologists (particularly Antonio Snider-Pelligrini, in France, and Richard Owen, in the USA) claimed that the continents were mobile. But their cases weren’t as compelling…
