Shell Shorts: A concise history of the Eames Shell Chair and how they are made today #ArtTuesday #manufacturing

Herman Miller has a great write up on the history of the iconic Eames Shell Chair as well as some fun animated gifs on how they are made today. Check out the full story here.

Below is some history of the chair written by Amber Bravo.

The story of the Eames Plastic Shell Chair really began more than ten years prior to Charles and Ray’s 1950 debut of their now iconic design for Herman Miller. Understanding this decade-long evolution not only helps shed light on Charles’ oft-quoted—“The details are not the details. They make the design”—it says a lot about the responsibility Herman Miller and the Eames Office and family have assumed at Charles and Ray’s request, to stay true to the designers’ tireless drive to improve and refine their designs.

The Eameses were notoriously material agnostic, and the seeds of the plastic shell we know and love today were really planted in the late ’30s, when Charles and Eero Saarinen first began exploring plywood seating in curved forms at Cranbrook Academy of Art, where Charles served as the head of the design department. Saarinen’s father, Eliel, was the head of Cranbrook and Eero was a junior partner at his father’s architecture office. It is likely that both Eames and Eero were influenced by the work of Finnish architect Alvar Aalto, who’d lectured at Cranbrook in the early ’30s and was well known for his bent plywood furniture. Eames and Saarinen’s first attempt at shaping plywood was realized in a chair concept for Eliel’s design for the Kleinhans Music Hall in Buffalo, NY, in 1939. While that chair had two-dimensional curves, their next design, an entry for The Museum of Modern Art’s “Organic Design” competition in 1940 had three-dimensional curves. For this they won first prize, but it was only produced in very limited numbers and not anywhere near to their desired quality. By this time, Charles had met and married Ray Kaiser, a student at Cranbrook, and the two moved to Venice, California to open their eponymous office. Eero abandoned the project, but Charles and Ray were determined to figure out a completely new process for molding plywood into compound curves.

Charles and Ray continued to experiment with their new technique for molding plywood, and their efforts yielded stretchers, lightweight, stackable leg splints (1942), and a glider seat (1943) for the U.S. Navy. When the war ended, they returned to the concept of a mass-produced chair. Despite their best efforts, they were still unable to produce a single-shell plywood form, but instead landed on a compelling alternative: a chair comprised of separate molded plywood panels for the back and seat, which would become the Eames Molded Plywood Chair (1946), which is still in production today and was subsequently named “Best Design of the Century” by Time magazine. Two years later, they produced a single form shell chair made out of stamped metal for Museum of Modern Art’s “International Competition for Low-Cost Furniture Design.” It took second place in the competition, but the, neoprene-coated prototype was too costly to produce, so Charles and Ray began looking into new materials like plastic reinforced with fiberglass, a material that could be molded into organic shapes and produced cost effectively, but had not yet been used in a consumer application before.

It was this iteration—released in 1950—that went on to become the first mass-produced plastic chair, but it was not the end of the design’s evolution. Through the years, color and height options, shock mounts, base variations, and choices of upholstery have redoubled, making the chair not only easily reproducible but also highly customizable. Manufacturing processes have also been closely monitored and modified, and, in the late 1980s, almost a decade after Charles’ death in 1978, the environmental implications of fiberglass production were called into question by Ray and Herman Miller. In the early 1990s, Herman Miller ceased production. After years exploring more sustainable solutions, the company reintroduced the Molded Plastic Shell Chair in 100% recyclable polypropylene in 2004, based on prototypes in the Eames Office archives, which Charles and Ray had made with fiberglass-free plastic in the 1970. In 2013, again working with the Eames Family, Herman Miller realized Charles and Ray’s vision for the shell chair design in a new and quite appropriate material—molded wood, thanks to advancements in the 3D veneer technology, and this year, the company has reintroduced the Shell Chair in a sustainably reformulated, Greenguard Gold Certified molded fiberglass as well as in upholstery.

Taking off where the Eames left off with their 1970 film, “The Fiberglass Chairs: Something of How They Get the Way They Are” WHY revisits the fiberglass production process in our fiberglass manufacturing facility in Ashtabula, OH and in Herman Miller’s own Greenhouse facilities in Zeeland, MI, in ten bite-sized videos, which we’ll be releasing over the course of two days on Instagram (along with some corresponding gif trailers below) and exploring the ways in which Herman Miller is honoring the Eames original design and ethos by pushing the manufacturing process and quality to be the best and most sustainable it can possibly be.
