"What has allowed so many Psychopathic Personalities to rise so high in corporations and government, is that they are so decisive. Unlike normal people, they are never filled with doubts, for the simple reason that they cannot care what happens next."
- Kurt Vonnegut, Jr.

| The first computer software drafting program (Computer Aided Design - CAD). |
This is the first mention of a computer software drafting program, like AutoCAD and the many other drafting packages available today.

This novel was published in 1956, which I believe was before the use of computers in drafting. In the mid-1950's the US Air Force developed SAGE (Semi Automatic Ground Environment) for air defense; it provided one key component; a cathode ray tube to show computer-processed information (in this case, radar and other data). The first true CAD (Computer Aided Design) systems emerged in the 1960's; the first was The Electronic Drafting Machine, which used PDP-1 computer from DEC (Digital Equipment Corp., a vector-refresh display and a disk memory device used to refresh the graphic display. An electronic light pen was used to input commands.
I spent some time working with PDGS (Product Design Graphics System), Ford Motor Company's home-grown CAD program. PDGS started with a few FORTRAN programs to calculate specific parameters for subsystems (like suspension designs); by the 1990's it had grown to a full-fledged system with (reputedly) 10,000 sub-menus full of features.
(Special thanks to Bill Mullins for pointing this one out.)
