[ih] what is NLS?

[Steve Crocker]

NLS was Doug Engelbart’s oNLine System.  He invented the mouse and pioneered the graphical user interface we use today.  There’s a direct line from his work to Xerox PARC to Apple.  I learned recently from Jeff Rulifson the reason for NLS instead of OLS: they had experimented with an offline version and they needed an acronym that differentiated between the two.

The first four sites on the Arpanet were UCLA, SRI, UCSB and the University of Utah, and it was Engelbart’s system at SRI that was connected, so it was a major influence right from the beginning.

There is a huge amount of information re NLS and Engelbart.  Look up “mother of all demos” and the 50th anniversary of the same which took place last December at the Computer History Museum in Mountain View, California.
