Professor Charles Anthony Richard Hoare, known as C.A.R. Hoare or Tony to friends, died at age 92. The British computer scientist invented the Quicksort algorithm and made fundamental contributions to programming theory. He was celebrated not only for his technical innovations but also for his wit and memorable quotes in the field.
Hoare's work shaped modern computer science, particularly in algorithm design and formal methods for program verification. His Quicksort algorithm remains one of the most widely used sorting methods in computing. Beyond technical contributions, he was known as a classicist and philosopher who brought intellectual rigor to programming.
