I just read that legendary designer Massimo Vignelli died today. Even if you don’t know his name, you’ve seen his work: the American Airlines corporate identity, the New York subway signage and map, furniture, books, packaging–it is all simple, elegant, and beautiful. He had a profound influence on design and designers over the course of his life.

Michael Bierut has an endearing tribute on the Design Observer site. Take a few moments to read it, then follow up on some of Vignelli’s work. Trust me: it will be worth your time.
