Sir Arthur C Clarke was, and is, a great author. His Science Fiction writing is some of the very best. Of his writings I have read:
The Sands of Mars (1951)
Islands in the Sky (1952)
Childhood's End (1953)
Earthlight (1955)
A Fall of Moondust (1961)
2001: A Space Odyssey (1968)
Rendezvous with Rama (1972)
The Fountains of Paradise (1979)
2010: Odyssey Two (1982)
2061: Odyssey Three (1988)
Rama II (1989) (with Gentry Lee)
Prelude to Mars (1965) (including Prelude to Space and The Sands of Mars)
Expedition to Earth (1953)
Reach for Tomorrow (1956)
Tales from the White Hart (1957)
Of Time and Stars (1972)
The Sentinel (1983)

And a lot of his other works. He is not only a great author, but he is also a great visionary. Considering the technology of his time, he imagined things that have come to pass, long before others even realized the possibilities.

And may I also say, that his effect upon my life, and my thinking, has been profound. Second only to Isaac Asimov, his writings have been instrumental in shaping my view of the Universe. I hope he sees his 100th birthday.
