Bless. I remember something controversial about him but not the details, think it was to do with an environmental issue about which he was passionate but his theories weren't quite right. Never mind about that, he was brilliant and a character. Botany is a beautiful science, pity there aren't more people who study it though I have read that Botany as a subject is having a renaissance (my uncle did Botany at Chelsea College of Science and Technology as it was before being incorporated into Kings, but not at same time as Bellamy who I believe was a mature student).
I'm glad he reached 86.
