Professor Knuth seemed to manage OK, writing TeX and METAFONT in Pascal

Indeed - problem was it was in a PDP-10/20 flavor and would compile on a Vax, without much hacking - I know I moved it once. It was a real PITA. Eventually folks would migrate to C implementations.

I suppose Apple's Pascal and Object Pascal -- used for Lisa and
Macintosh applications and systems software -- comes under the "so
people fixed it" category?

That was the issue, everyone 'fixed it' and the fixes were all all different. Eventually market place pressure of the PC made Turbo Pascal enough of a standard because so many people were using it, but by that time, the war had been lost.

All the things Brian points out that made C great, made it the language commercial folks used for both the PC and UNIX.
