At PARC Chuck Geschke and John Warnock designed the Interpress device-independent page description language supported by Xerox printers and other systems, including Interlisp-D. This work was the foundation for PostScript, which Geschke and Warnock developed at their startup Adobe after leaving PARC.

Chuck Geschke was a #XeroxPARC employee, #pioneer of #computergraphics, #WYSIWYG, and page-description languages. As co-founder of Adobe Systems, father of #PostScript and #PDF-files* the impact of his work is literally everywhere. (*not to be confused with pedophiles like Jeffrey Epstein)

Those #vectorgraphics are known as #infographics or #schematics to a few #computer #graphic #geeks. #IT's how #SuperPaint worked #1973 for the first #digital #artists. Deeply embedded #CGI #irony is that this #legendary #image-editor is reconstructed in #vector #tech, not #pixel. The #Art work isn't realized with #Xerox #InterPress, nor #Adobe #Illustrator / #PostScript, but made with #opensource #FreeSoftware #Inkscape and #SVG
The legendary #Xerox 9700 #laserprinter with closed-source #interpress #RIP #software inspired #RichardStallman to write the #GPL and start the #FreeSoftware movement.

Of course, this #SVG #vector #graphic #illustration and #FOSS #artwork is made with #Inkscape, not #Adobe #Illustrator
