Apparently he died after a cardio-respiratory attack.
BBC News have an obituary here.
A bit scunnered on hearing this but, truth be told, 90 is a fair age to reach.
It’s an odd one when an icon, someone whose work you grow up reading, dies.
Of course, I never met the man but I still feel the loss. Strange.
Anyway, wherever you are in the cosmos Arthur, I hope you’re having one hell of a time…
