That title is a bit much. Did Dijkstra do so more than Wirth? Hoare? Backus? Knuth? von Neumann? Maybe, maybe, maybe, no, and definitely no. Dijkstra had some real achievements. He was one of the giants, no doubt. But he wasn't the giant. He was highly opinionated. He had his way of working, and anybody who did it any other way was wrong (and probably either stupid or lazy). That's not the optimal route to improving a field, especially when you aren't 100% right.
