Frederic Goudy had one, so did Philip Johnson and Robert Rauschenberg. The Eameses had two. Pentagram is awash in them. George Lois wears his to bed. We’re talking about AIGA Medals, the graphic design world’s highest honor. This year, the AIGA is celebrating its centennial by bestowing medals on 24 design visionaries that “together exemplify the legacy of visual communications and the impact of design”: Sean Adams and Noreen Morioka, Richard Danne, Alexander Isley, Charles S. Anderson, Michael Donovan and Nancye Green, Chip Kidd, Dana Arnett, Stephen Doyle, Michael Mabry, Kenneth Carbone and Leslie Smolan, Louise Fili, Abbott Miller, David Carson, Bob Greenberg, Bill Moggridge, Kyle Cooper, Sylvia Harris, Gael Towey, Michael Cronan, Cheryl Heller, and Ann Willoughby. They will be presented with their James Earle Fraser-designed medals on April 25 at the AIGA Centennial Gala in New York City.
