Gave us
Dijkstra's algorithm (shortest path). The semaphore. Structured programming. The "GOTO considered harmful" letter.

Dutch, opinionated, and unapologetically theoretical. Wrote his EWDs (Edsger W. Dijkstra notes) by hand in numbered, dated essays — over 1300 of them.
"Computer science is no more about computers than astronomy is about telescopes."
