This pick should come as no surprise - Gates has not been shy about his admiration of Smil's work. On his Gates Notes blog, he said that he has read nearly all of Smil's 37 books, most of which delve into topics like food production, energy, public policy, and the environment.
"The truth is, I'd read just about any topic he found interesting and wanted to dissect," Gates wrote of the Czech-Canadian scientist.
