Alfred Aho

Alfred Vaino Aho is a Canadian computer scientist whose work at Bell Labs includes co-creating the AWK programming language and co-authoring the foundational "Dragon Book" on compiler design with Jeffrey Ullman. His research established the theoretical foundations for efficient string matching and parsing that underpin every modern programming language implementation.

Aho's contribution to computing is not merely technical but pedagogical. The decline of rigorous compiler education in computer science curricula is a loss that will not be felt until the generation that never read the Dragon Book tries to design a language.
