Matthew Carter is a man whose work you most likely rely on, but whose name you likely do not know. The Babbage blog over at The Economist call him "The most-read man in the world."
He is the creator of the ubiquitous Georgia and Verdana fonts, among many others, and is also a 2010 MacArthur Fellow (a genius!). Babbage introduces him this way:
Mr Carter sits near the pinnacle of an elite profession. No more than several thousand type designers ply the trade worldwide, only a few hundred earn their keep by it, and only several dozens — most of them dead — have their names on the lips of discerning aficionados.
The MacArthur Foundation produced this short video (below) that portrays Carter in his own words. It's a good companion to The Economist's appreciation of this amazing artist.
