Very sad to hear that Adrian Frutiger has passed away. He’s been phenomenally inspirational to me and I always had a weird little connection in that we share the same birthday (give or take 60 years).
Aside from his type design, books of his such as “Type Sign Symbol” and “Forms and Counterforms” were a great influence while working on my thesis. No doubt about it, he’s left a legacy.
The image in this post shows various styles and weights of Univers, one of Frutiger’s most famous typefaces. Aside from its fantastic readability, Univers was also groundbreaking for its naming/numbering conventions.
