Mark Twain was a suppose the best known author to have been employed as a typographer. For that matter, one of the vagabonds in Huckleberry Finn, I forget whether Duke or Dauphin, evidently knows his way around the type case and the press.
The Monotype System must have been one of the earliest uses of paper tape for encoding information--see https://en.wikipedia.org/wiki/Monotype_System .
It's amazing how interlinked typesetting and computing are. Here we have a troff link, then there's the PDF (from postscript) and TeX world, keyboard layouts, telegrams, rotating drums and early mechanical cryptography, etc.
If anyone's interested in good collections on the history of printing, I can recommend both the Museum of Printing and Graphic Communication (Musée de l’imprimerie et de la communication graphique) in Lyon, France[1] and the National Technical Museum (Národní technické muzeum) in Prague, Czech Republic,[2] which also sports the best permanent exhibition on the history of photography I have ever seen (by a long shot). For those of you in California, there's also the International Printing Museum[3] in Carson (open 10-4PM Saturdays).
