System Software 1.0 (System 3.1/Finder 5.2, Feb. 1986) for the 512K is presumably not what you wish to know about, given your usual research instincts, so I was driven back to Cary Lu's book for the authorship of System 1.0.

Certainly this embraced applications, but I cannot corroborate my long-held remembrance that Gates, inter alia perhaps, had a hand in coding the System.
What Lu's book (1984) did reveal was this:
Lu goes on to hint at, but not forecast, future developments with the statement that the MC68000 can directly address up to 16MB of RAM.
