Here's a long shot of a guess. I don't think the Norwegians will award a Peace Prize this year. Still reeling from the horrible Utoya massacre, they may just put it on hold this year to honor the silenced dead. It might be a fitting gesture.
Of course the Swedes award the science prizes. One name I've always been surprised to see passed over in Chemistry (as if I'm a judge of such things) is Carl Djerassi, co-inventor of the first oral contraceptive for women back in 1951. He had a long career at Stanford University (he's since retired). He's also long been interested in the arts and even writes fiction. Djerassi didn't accomplish the Pill on his own, but many of the important others are now dead and thus ineligible. My casual read of Wikipedia suggests that George Rosenkranz could be a co-contender.
Djerassi foresaw the Pill's huge social impact, anticipating a far greater social impact on men than on women. He apparently also foresaw the so-called "feminization of men," along with changes in laws and social values in favor of women in society as a whole. link
