Again, the passing of one of CS heroes. /Computers and Intractability/ was one of the first CS books I bought. The anecdote they open with, about coming to your boss claiming "I can't find an efficient algorithm, I guess I'm just too dumb" (as opposed to proving that the problem is NP-complete: "i can't find an efficient algorithm, but neither can all these famous people") is still one of my favorite teaching stories.
