I'd hazard to guess that most of the names (by volume) which appear in history textbooks are pretty much unknown. Who knows, maybe I'm just one of today's lucky 10,000 - but this is the first time I've ever heard of anyone actually talk about this guy.

I have heard "MacArthur Fellows" before, so to me this is a bit like the only reason I can tell you Alfred Nobel invented dynamite is because people mention it in connection with the Nobel prize - so maybe they both succeeded in the end!
