When Jeopardy! champ Ken Jennings was seven years old, he bought an atlas: it was his passion during the day, and at night it was his teddy bear, tucked under his pillow. He says he was a weird kid. I identify with that–I was kind of a weird kid myself, now I’m a huge map nerd. That’s where we intersect, me and Ken. Where we hugely diverge is that he’s a best-selling writer/famous polymath, and I’m a gnome-like manuscript map-and-globe maker. No grudges, though: in fact I urge you all–map nerds and generalists alike–to read his wonderful & amusing book Maphead, now available in paperback. For a little preview, listen to a 9/21/2011 interview with Jennings on NPR’s Fresh Air, or read his blog, Ken Jennings: Confessions of a Trivial Mind.
