Feng-hsiung Hsu (born January 1, 1959) (Chinese: 許峰雄; pinyin: Xǔ Fēng Xióng) (nicknamed Crazy Bird) is a Taiwanese-American computer scientist and the author of the book Behind Deep Blue: Building the Computer that Defeated the World Chess Champion. His work led to the creation of the Deep Thought chess computer, which led to the first chess playing computer to defeat grandmasters in tournament play and the first to achieve a certified grandmaster-level rating. Hsu was the architect and the principal designer of the IBM Deep Blue chess computer. He was the recipient of the 1990 Mephisto Best-Publication Award for his doctoral dissertation and also the 1991 ACM Grace Murray Hopper Award for his contributions in architecture and algorithms for chess machines.
