After his tour of Europe and North Africa, Saarinen returned to Cranbrook to work for his father and teach at the academy. His father’s firm, Saarinen, Swanson and Associates, was headed by Eliel Saarinen and Robert Swanson from the late 1930s until Eliel’s death in 1950 and headquartered in Bloomfield Hills, Michigan until 1961 when the practice was moved to Hamden, Connecticut.
While still working for his father, Saarinen first gained recognition for his design capabilities for a chair he designed together with Charles Eames, which received first place in the Organic Design in Home Furnishings competition in 1940. The Tulip chair, like all other Saarinen chairs, was taken into production by the Knoll furniture company, founded by Hans Knoll, who married Saarinen family friend Florence (Schust) Knoll. Further attention came also while Saarinen was still working for his father when he took first prize in the 1948 competition for the design of the Gateway Arch National Park (then known as the Jefferson National Expansion Memorial) in St. Louis. The memorial was not completed until the 1960s. The competition award was mistakenly addressed to his father because both he and his father had entered the competition separately.
During his long association with Knoll he designed many important pieces of furniture, including the Grasshopper lounge chair and ottoman (1946), the Womb chair and ottoman (1948),[6] the Womb settee (1950), side and arm chairs (1948–1950), and his most famous Tulip or Pedestal group (1956), which featured side and arm chairs, dining, coffee and side tables, as well as a stool. All of these designs were highly successful except for the Grasshopper lounge chair, which, although in production through 1965, was not a big success.
One of Saarinen’s earliest works to receive international acclaim is the Crow Island School in Winnetka, Illinois (1940). The first major work by Saarinen, in collaboration with his father, was the General Motors Technical Center in Warren, Michigan, which follows the rationalist design Miesian style, incorporating steel and glass but with the addition of accent of panels in two shades of blue. The GM Technical Center was constructed in 1956, with Saarinen using models, which allowed him to share his ideas with others and gather input from other professionals.[7]
With the success of this project, Saarinen was then invited by other major American corporations such as John Deere, IBM/IBM Rochester, and CBS to design their new headquarters or other major corporate buildings. Despite the overall rational design philosophy, the interiors usually contained dramatic sweeping staircases as well as furniture designed by Saarinen, such as the Pedestal series.[8] In the 1950s, he began to receive more commissions from American universities for campus designs and individual buildings. These include Birch Hall at Antioch College, the Noyes dormitory at Vassar and Hill College House at the University of Pennsylvania as well as the Ingalls ice rink, Ezra Stiles & Morse Colleges at Yale University, the MIT Chapel and neighboring Kresge Auditorium at MIT and the University of Chicago Law School building and grounds.
Saarinen served on the jury for the Sydney Opera House commission in 1957 and was crucial in the selection of the now internationally known design by Jørn Utzon.[9] A jury which did not include Saarinen had discarded Utzon’s design in the first round; Saarinen reviewed the discarded designs, recognized a quality in Utzon’s design, and ultimately assured the commission of Utzon.[9]
After his father’s death in July 1950, Saarinen founded his own architect’s office, Eero Saarinen and Associates. He was the principal partner from 1950 until his death. The firm carried out many of its most important works, including the Bell Labs Holmdel Complex in Holmdel Township, New Jersey; the Gateway Arch in St. Louis, Missouri; the Miller House in Columbus, Indiana; the TWA Flight Center at John F. Kennedy International Airport, which he worked on with Charles J. Parise; the main terminal of Washington Dulles International Airport; and the new East Air Terminal of the old Athens airport in Greece, which opened in 1967. Many of these projects use catenary curves in their structural designs.
In 1949 and 1950, Saarinen was hired by the then-new Brandeis University to create a master plan for the campus.[10] Saarinen’s plan A Foundation for Learning: Planning the Campus of Brandeis University (1949; second edition 1951), developed with Matthew Nowicki, called for a central academic complex surrounded by residential quadrangles along a peripheral road.[11] The plan was never built but was useful in attracting donors.[10] Saarinen did build a few residential structures on the campus, including Ridgewood Quadrangle (1950), Sherman Student Center (1952) and Shapiro Dormitory at Hamilton Quadrangle (1952).[11][10] These have all been either demolished or extensively remodeled.[citation needed]
One of his best known thin-shell concrete structures is the Kresge Auditorium at MIT. Another thin-shell structure is Ingalls Rink at Yale University, which has suspension cables connected to a single concrete backbone and is nicknamed “the whale”. His most famous work is the TWA Flight Center at John F. Kennedy International Airport, which represents the culmination of his previous designs and his genius for expressing the ultimate purpose of each building, what he called the “style for the job”.[12][page needed] In 2019, the terminal was transformed into the TWA Hotel and features furniture designed by Saarinen.[13][14][15]
Saarinen designed the Kleinhans Music Hall in Buffalo, New York, together with his father, Eliel Saarinen. He also designed the former Embassy of the United States in London, which opened in 1960, and the former Embassy of the United States in Oslo.
Saarinen worked with his father, mother, and sister designing elements of the Cranbrook campus in Bloomfield Hills, Michigan, including the Cranbrook School, Kingswood School, the Cranbrook Art Academy, and the Cranbrook Science Institute. Eero Saarinen’s leaded-glass designs are a prominent feature of these buildings throughout the campus.
