Actually, string theorist John Schwarz now occupies Richard Feynman's old office at Caltech. But... I got Feynman's desk.
Caltech has a room devoted to Feynman memorabilia, and they really want this desk. (Feynman-worship is quite the industry here; the bookstore has a section labeled "Feynman" in the same way an ordinary bookstore would have sections labeled "Physics" or "Women's Studies.") But Helen Tuck, who was Feynman's secretary and still occasionally visits, insists that the desk be used by a working physicist. My impression is that the desk is given to the most senior person in the theory group who is not sufficiently senior to get all brand-new fancy furniture; at the moment, that person is I. (In the background, one can discern the winner of the ultimate showdown.) I looked for little diagrams carved into the wood, but haven't found any yet.
