So what do Mobile, Xerox, PBS, Chase Manhattan Bank, and National Geographic all have in common? Their graphic identity programs were designed by New York-based designer Tom Geismar. Along with long-time partner Ivan Chermayeff, the firm now known as Chermayeff & Geismar & Haviv has been producing groundbreaking graphic design since the late 1950s. The School of Visual Arts recently honored Geismar with the 26th annual Master Series Award and Exhibition. On a recent trip to New York City, my wife Linda and I enjoyed viewing the work of this legendary designer.
