I believe the document I'm thinking of may have been RFC 1480

https://www.ietf.org/rfc/rfc1480.txt

If so, the other person was Ann W Cooper

AFAIK Cooper was never at SRI, but Postel was at one time

Putting aside the inaccurate memory, the point I wish to make as an ordinary computer user reading about the internet is that Postel wrote about the internet as a _public resource_. Check out the tone of this random Postel RFC, for example

https://www.ietf.org/rfc/rfc1591.txt

Postel received a PhD in Computer Science in 1974 from UCLA and, apparently, he was a _two-finger typist_ who preferred handwritten slides over PowerPoint and used monochrome logos instead of color (I find this interesting; I'm not suggesting anyone else would)

Joyce K Reynolds, who co-authored some of the most important RFCs with Postel on protocols, was a social sciences major (another factoid I find interesting)
