He died today in Sri Lanka at the age of 90.
He is best known as the author of 2001: A Space Odyssey, which at the time was a groundbreaking science fiction film; the first film to break away from pointy sheetmetal clad spaceships and flying saucers. I refer to the movie/book simultaneously because the movie was actually written before the book in collaboration with legendary director Stanley Kubrick.
Really I don't know what to say about such an influential and inspirational man... if you would like to leave a comment about how he has affected or influenced you, please do.
