John Jackson pioneered international trade law, helped to establish the WTO, and taught legions of professors and trade policy officials who continue to promote his goals of a multilateral trading system based on the rule of law, transparency, fairness, and non-discrimination. A great man, he was also a very dear man – humble, quiet, unassuming, kind, and private. In his writings, he had the unique ability to distill very complex issues down to a few, readily comprehensible paragraphs for students and readers.
