From boiling lead and black art: The history of mathematical typography (2017)

Great article. I have a big soft spot for typography, so learning that (La)TeX effectively emulates monotype's setting capabilities and practices was fascinating.

For others looking for the Moby Dick comparison PDF (the link in the article is broken), it has moved here: http://www.rtznet.nl/zink/comparison.pdf

Hey, DVI was my suggestion and initial implementation; Knuth's comments in the TeX source code acknowledge this, and they mention plenty more people than Frank Liang who made significant contributions to TeX82: Leo Guibas, Michael Plass, Lyle Ramshaw, Robert Sedgewick, Luis Trabb Pardo, Howard Trickey, Doug Wyatt, and Ignacio Zabala.

Didn't know equation-heavy text was called penalty copy. The expense moved from typesetters to whoever has to learn LaTeX.
