Who knows the story to that specific invention, but I imagine a lot of people invent things that they already have a huge interest in. They've already spent time thinking about that area of knowledge involving that invention, and then they have the idea. Then perhaps they need to learn more to manifest the invention, but once they have the idea, they're even more driven to learn than before. I find it less likely that someone would be completely detached from the field of knowledge required for an invention, and then learn EVERYTHING more or less and finally making it a reality after like a decade or something.
