      Giving Credit where Credit Is Due

      ACM recognizes excellence through its eminent awards for technical and professional achievements and contributions in computer science and information technology. It also names as Fellows and Distinguished Members those members who, in addition to professional accomplishments, have made significant contributions to ACM's mission. ACM awards recognize achievements by young computing professionals, educators, theoretical computer scientists, software systems innovators, and pioneers who have made humanitarian and cross-discipline contributions.
