Happy Birthday Massimo Vignelli! He is 82 today, and definitely one of the great living designers. A modernist and a purist, as well as graphic design he has also been involved in many other disciplines including product and furniture design, which is lucky considering he is famous for saying among other things; “If you can design one thing, you can design everything.”
You can find more of his work here, plus lots more about him in this excellent post on Brain Pickings. But most of all you should read The Vignelli Canon, a free E-book published online back in 2009.
