I remember Jim as one of the tall figures at IUCN headquarters. Soft spoken, immensely knowledgeable, with deep convictions on nature protection that he defended on the international scene with a rare intelligence and a real courage against forceful lobbies. I also remember his unique sense of humour (for ex. replacing on his desk the photo of his girlfriend with that of his horse in his beloved Canadian Rockies, so as to signify the turn of a sentimental chapter in his life). We will miss him.
