Unimark International was an international design firm headquartered in Chicago, Illinois. It was founded in 1965 by seven partners: Ralph Eckerstrom, Lella and 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. Later, a London office was opened in Dover Street and was run by Jan Stael von Holstein. The American branches were founded by Vignelli and his wife Lella, who subsequently founded Vignelli Associates. 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.
