I was at Stanford when Prof Knuth developed his TeX system in the 1980s. It was wonderful to watchthe user group meetings develop these systems. For themost TeX semed to spring in a fully developed fashion like Athena born from the head of Zeus. At the same time as TEX Knuth developed literate programming. It was a method of writing code and documentation simultaneously with empathsis on the latter. The main disappointment with TeX is that it postponed Knuth finishing his algorithms magus opus The Art of Computer Programming by a decade or so. And perhaps unfinished in his lifetime.
