I recently took a Type Design class and this was made during that. I'm originally a Visual Designer, always loved picking fonts and searching for those with personality so I took a class.
1. A text typeface with a high x-height.
2. Aimed somewhere between UI and Print(did some print proofs and kinda looks ok even under 10pt).
3. A bit of personality but not too in the readers face.
4. Elegant but not serif.
5. Full formed numbers.
*also dropped in some alternatives.
So this were my criteria when I started, I don't have any historical reference what so ever.
Kerning is still in progress.
Thanks in advance for taking the time.
