What should be included in a history of the Rust language?

I am working on writing a brief history of the Rust language and its development. I wondered if I could crowdsource some ideas on what that should entail.

As a starting point, here are some of the ideas I am looking at digging into:

• Key people - profiling some of the early and most influential contributors (i.e. Graydon Hoare)
• Key companies and sponsors (i.e. Mozilla)
• Early use cases and applications
• Key turning points in the language design (This one is especially difficult as I'm not sure how deep to go on certain RFCs, etc.)

What am I missing here?

Also, if anyone has resources they could point to for info on any of these things, that would be much appreciated!
