Here's another entry that's a bit unorganized. It's also a bit more of a recent (and sometimes older) history related things that I learned about mostly through HN. Replies / additions to this are welcome.
__Lisp (programming language)__
The Structure and Implementation of Computer Programs (you need to use a search engine for this, there are many different versions of it).
Anything Paul Graham wrote about Lisp (e.g. http://www.paulgraham.com/avg.html)
__Hacking__

__Smalltalk (programming language)__
Alan Kay Smalltalk is not about objects, it's about messaging: https://news.ycombinator.com/item?id=21852444
Smalltalk is awesome and one of the historical predecessors of Objective-C.
__Xerox Parc__
Unfortunately, I don't know of any seminal paper or media piece. I just know they were hugely influential. See: https://en.wikipedia.org/wiki/PARC_(company)
Alan Kay worked there.
