In 2001: A Space Odyssey by Arthur C. Clarke, Hal was a computer developed by the H A L Labratories in Urbana, IL. The computer known as Hal was of the HAL 9000 series of computers. Hal was said to be artificially intelligent. This series of the computer was never known to make an error, and Hal cosidered himself to be perfect. His crewmates Frank Poole and David Bowman thought well of him, until Hal killed Frank (who was brought back to life in 3001: the Final Odyssey).
