It`s a really sad day to lose someone like him. I read lots of his books when younger. He retained his enthusiasm and wonder at the universe and life to the end.
I love his work, especially novels like 'Fahrenheit 451' and 'The Martian Chronicles'. His short stories were excellent too, such as 'The October Country' and 'The Pedestrian'; his writing for 'The Twilight Zone'.
'Fahrenheit 451' is striking as he depicts an affluent, technologically advanced society like the USA as a dystopia/dictatorship; in stark contrast to European writers who tend to see and think them as poverty stricken; such as George Orwell in '1984'.
The movie version of 'Fahrenheit...' is one of the few novels made into a film that actually works artistically. The book has more bite, but the director did manage to capture the essence of the novel. The image at the end of people becoming a book by learning the text (to save them) is one I`ll never forget.
