Here's the beginnings of a draft of the Scandinavian 81. For the moment, I'll content myself with the top 27. Each name links to the subject's wikipedia page. One day, I hope, this project will morph into a full-fledged, moderated wiki of its own.

I'm nowhere near satisfied with this yet, probably I never will be. I'm not certain that it's even possible to rank individual human beings in terms of their historical influence, even within the same field, much less between fields as various as science, cinema, politics, literature, art. But my reservations won't stop me from trying. If anything, they spur me on.
