I'm very sorry to hear the news of Jim's passing. He was a giant in the world of World Heritage when I first started attending meetings on behalf of ICCROM. I remember the good-natured teasing between Jim and Henry Cleere of ICOMOS about whether cultural or natural heritage was more important to the Convention. Jim would often laugh at a picutre of an archaeological site and call it "a pile of rocks". In the end, they were both right. RIP Jim.
