Prototype Eames Fiberglass Chair, circa 1949

Charles and Ray Eames wanted to design affordable high-quality furniture. To this end, Charles brought a mock-up of a chair to John Wills, a boat builder and fiberglass fabricator, who created two identical prototypes. Charles took one: it became the basis for what would become a modern design icon. This is the other: it lingered in Will's workshop, used over four decades as a utility stool.
