I've been exploring various aspects of modernization in technical communication. The history of blueprinting seems amazingly under-told. Blueprinting is an example of representational technology that led to a change in practices of everyday professionals. There seems to be some sort of McLuhan/Ong/Innis thing combined with a dash of Benjamin/Adorno.
There are a few traces of this obscure history. Archive.org, for example, has copies of some old drafting texts and there are a few online resources such as this one from the Charlestown Blueprint Company and another one reprinted from Modern Reprographics.
Another interesting tidbit comes from a biography of Elmer Carl Kiekhaefer, founder of Mercury Marine (now part of Brunswick). In 1926 Elmer went to work at the Nash Motors Body Division. As noted by Rodengen, it was "his first job that required clean hands and shoes, a pressed shirt and tie, and an eight-to-five schedule." (p. 38) He began to work through the ranks of the drafting and blueprinting section. Rodengen describes his rise through the ranks:
"from delivering materials and specifications to the various drafting benches as an office boy, to blueprint boy, assisting the blueprint section in converting the many hundreds of drawings required for each automobile into the familiar white-line, Prussian-blue-background duplicates that could be sent to the toolmakers, outside vendors, plant engineers, prototype builders and engineering departments. He would check the accuracy of the blueprints against the original drawings before they were sent out to their destinations. His keen eye for detail, combined with his basic engineering skills, earned an early promotion to drawing detailer. He was then allowed to actually contribute his marks to drawings, detailing various minor areas of body panels, fenders and hinge mechanims, as well as illustrating rudimentary electrical system routing and termination. Eventually, as a layout draftsman, he was permitted to execute complete drawings, using the stringent specifications established by the engineering department." (p. 38)
