The Paris Kanellakis Theory and Practice Award is granted yearly by the Association for Computing Machinery (ACM) to honor specific theoretical accomplishments that have had a significant and demonstrable effect on the practice of computing. It was instituted in memory of the computer scientist Paris Kanellakis, who died with his immediate family in an airplane crash in South America in 1995 (American Airlines Flight 965). The award is accompanied by a prize of $5,000 and is endowed by contributions from the Kanellakis family, with additional financial support provided by ACM`s Special Interest Groups on Algorithms and Computational Theory (SIGACT), Design Automaton (SIGDA), Management of Data (SIGMOD), and Programming Languages (SIGPLAN), the ACM SIG Projects Fund, and individual contributions.
