Chip Kidd is currently associate art director at Knopf, an imprint of Random House. He is known for the book covers he has designed. There is a great video of a talk he gave at Google. The first ten minutes is about his new book that he wrote but the final fifty minutes is about book covers he has designed. He show slides of the different covers and talks about the thought process to create them. He also shows several slides of covers that never made it to production. This is interesting because you get to see what the cover to "The Road" might have been if Cormac McCarthy had liked the first proposal. Video here.
