Knuth built TeX in 1977 to fix broken digital typesetting of his own book; Lamport’s LaTeX macros on top turned it into the standard for all scientific publishing.
Key Takeaways
Knuth started TeX after Addison-Wesley’s switch to cheaper electronic typesetting degraded galley proofs of The Art of Computer Programming volume 2.
TeX is extensible via macros; Lamport’s lplain macro set became LaTeX, adding high-level commands that separated content from presentation and drove mass adoption.
Knuth froze the TeX engine in 1992 and required any modified version to pass an automated conformance test before using the name TeX, preserving manuscript compatibility across decades.
Cornell’s arXiv receives over 10,000 LaTeX manuscript submissions per month, making TeX the de facto interchange format for physics, math, and CS research globally.
WYSIWYG desktop publishing took over nontechnical publishing; TeX’s command-line model stayed dominant in technical fields precisely because precise glyph placement is non-negotiable there.
