In the Who Knew? category, we offer the World Food Prize, won this month by former senators and presidential candidates George McGovern and Bob Dole, whose eight-year-old international school feeding program has helped 22 million kids, especially girls. The prize is the brainchild of 1970 Nobel Peace Prize winner Norman Borlaug, credited for a life of fighting hunger and starting the "green revolution" of expanded farming worldwide with disease-resistant plants. The reason: After winning, Borlaug realized there was no Nobel category for agriculture issues, so he set up his own award, now endowed, that pays a $250,000 prize. It's very likely little known outside the Midwest because it's based in Des Moines. But Iowa Sen. Charles Grassley assures us: "It's to be the equivalent of the Nobel Prize."
