The design firm headed by Ivan Chermayeff, Tom Geismar, and Sagi Haviv specializing in visual identity and brand design, art in architecture, motion graphics and exhibit design. Responsible for hundreds of the most famous trademarks in the world such as Mobil Oil, Chase bank, PBS, Viacom, Showtime, National Geographic, NBC, Barneys New York, Univision, Xerox, Cornell and Brown universities, Museum of Modern Art, and many more.

Ivan Chermayeff and Tom Geismar initially formed their partnership in the late 1950s with the idea of working collaboratively and in a wide range of disciplines. Over the ensuing years, their work has remained consistent not in style but in its approach to design. Accepting the Modernist principle that design is a problem-solving discipline, they have sought to humanize that ideal through humor, artistic invention, and an entrepreneurial spirit.

As their firm evolved over the years, they have operated under various versions of the Chermayeff & Geismar name. In 2006, designer Sagi Haviv became the firm's third partner. The timeline linked below highlights many of the outstanding projects achieved in over five decades of activity.
