Unimark International was an international design firm headquartered in Chicago, Illinois. It was founded in 1965 by six partners: Ralph Eckerstrom, Massimo Vignelli, Bob Noorda, James Fogelman, Wally Gutches, and Larry Klein. Although they were not listed as founding partners, Jay Doblin and Robert Moldafsky joined the new firm almost immediately. Initially, Unimark had three offices: Chicago, Milan and New York. Additional offices opened around the world, but these were often short-lived as the client base and funding varied, and as American and global economic issues influenced the viability of each office.
Unimark downsized dramatically in 1972 and filed for final Chapter 11 bankruptcy in 1977. It no longer exists. Although the firm was relatively short-lived, it was at one time the largest design firm in the world, and it had a major influence on the direction of American design aesthetics. The firm was a leader in establishing a modernist philosophical direction for corporate design that is still widely followed. Former Bauhaus designer Herbert Bayer was an early member of the firm's Board of Directors. The graphic style of Unimark's projects was decidedly modernist. Unimark rejected the idea of the designer-as-artist, embraced standardization and systems and emphasizing the use of the grid as an organizational tool for corporate communications. The typeface Helvetica was widely, though not exclusively, used by Unimark designers.
The firm was an early specialist in designing corporate identity systems, branding, and signage systems. Clients included American Airlines, Ford Motor Company, Gillette, JC Penney, Knoll, and the New York Transit Authority who continue to use Unimark-created trademarks and graphic standards.
