Examples of how meaning has been embodied into past typeface designs

I’m currently researching into how meaning has been embodied into typeface designs. I’m looking for typefaces which have an extensive and purposeful meaning behind their designs. Sufficient enough to write a thousand words about.

I need six case studies in total, so far I have Times New Roman, Capitolium, Johnston and Quantange. All of which I believe have enough existing research and theories into why and how they have been designed in the way they were. Ideally I need two more.

I posted a brief similar question to this many months back during my initial research phase. I was sent in the direction of Nick Shinn and Jeremy Tankard’s work, and FUSE, and they all really helped a lot.
