In Memoriam: Paul Karger

V.S. Naipaul\´s latest book cites an African saying: "When an old person dies, we say a library has burnt down." Paul Karger was far from old, and he had not only an encyclopedic (and bibliographic) knowledge of our field but also the ability to apply it to new situations. We have indeed lost a library, and more, with Paul\´s passing in September. In recognition of his impact on the field, IEEE S&P solicited the following tribute from a few of his many colleagues and friends.
