Knuth? https://cs.uwaterloo.ca/~shallit/Courses/134/history.html claims it was George Forsythe who coined the term, and Knuth's http://icme.stanford.edu/system/files/file-insertions/forsyt... seems to collaborate that (second page, top of left column)

Back to the subject at hand: reading TAOCP front to back isn't for everybody (reading it is way easier if you have a good understanding of combinatorics and number theory), but I enjoyed it, and learned a lot from it.

I wouldn't expect anyone to read TAoCP front to back either. It isn't finished. We've only got the first part of chapter 7 and none of chapters 8 through 12. On the other hand, it's the best rabbit hole out there for the non-layman.
