From a lecture by Donald E. Knuth dedicated to George Pólya on his 90th birthday. This is one of the first explanations by Knuth of the TEX and METAFONT software tools which have over the last 40 years completely transformed how scientific papers with heavy mathematical content are composed and typeset.
In his paper he explains how he hoped that TEX would one day be used:
Perhaps some day a typesetting language will become standardized to the point where papers can be submitted to the American Mathematical Society from computer to computer via telephone lines. Galley proofs will not be necessary, but referees and/or copy editors could send suggested changes to the author, and he could insert these into the manuscript, again via telephone.
