It was home to Einstein in decline, the place where Kurt Göedel starved himself in paranoid delusion, and where J. Robert Oppenheimer rode out his political persecution in the Director's mansion. It is the Institute for Advanced Study in Princeton, New Jersey; at one time or another, home to fourteen Nobel laureates, most of the great physicists and mathematicians of the modern era, and two of the most exciting developments in twentieth-century science—cellular automata and superstrings. Who Got Einstein's Office? tells for the first time the story of this secretive institution and of its fascinating personalities.
