Maybe that's because I am 5th or so generation descendant of Hilbert but then again why wouldn't other CS PhDs also have a Mathematics grandfather++ when they go back long enough?
[1] Edsger Wybe Dijkstra was a Dutch computer scientist. A theoretical physicist by training, he worked as a programmer at the Mathematisch Centrum from 1952 to 1962. Wikipedia
Granted, Dijkstra did make some contributions to CS, but he also caused immense damage to CS education by promoting his vision of CS as exclusively a branch of applied mathematics, instead of an engineering discipline employing mathematics as one of several tools. That mentality has led to much preaching about constructing programs using top-to-bottom formal methods, and very few useful programs constructed that way.
Can I quote you as a reference when arguing on the Internet that our OS concepts do not owe anything to Djikstra, who was only jetting between conferences? It sounds like you are pretty sure.
This trend kind of worries me.
