John Jackson was one of the giants in trade law, with Robert Hudec (who died some years ago) as his equal, though their abilities and interests nicely complemented each other. They both were read with profit, along with other luminaries such as Michael Trebilcock of Toronto, by economists such as myself. They also inspired modern trade-law stars such as my colleagues Petros Mavroidis, David Leebron at Rice, and Alan Sykes at Stanford.
