Living in the apartment where the Eames prototyped their first designs in the 1940s, I've always been fascinated by the subtle changes iconic pieces undergo as they are first put into production and later revived. Herman Miller, which began as a traditional Michigan furniture maker, was introduced to modernism by Gilbert Rhode in the 1930s, and again by George Nelson, who was their director of design, 1945-1972, a tenure no-one is ever likely to match. He designed an entire range of basic furniture himself in a year, and then brought in his friends, Charles and Ray Eames, who have been the company's household gods ever since. Over the years, as Herman Miller put a greater emphasis on the contract market, some of the Eames's designs went out of production. A few were pirated, European rights went to Vitra, but most of the drop-outs have been brought back in sparkling new editions.
