The Architects Collaborative (TAC) was an American architectural firm formed by eight architects that operated between 1945 to 1995 in Cambridge, Massachusetts. The founding members were Norman C. Fletcher (1917–2007), Jean B. Fletcher (1915–1965), John C. Harkness (1916–2016), Sarah P. Harkness (1914–2013), Robert S. McMillan (1916–2001), Louis A. McMillen (1916–1998), Benjamin C. Thompson (1918–2002), and Walter Gropius (1883–1969). TAC created many successful projects, and was well respected for its broad range of designs, being considered one of the most notable firms in post-war modernism. History Norman Fletcher, Louis McMillen, Robert McMillan, and Ben Thompson first laid the conceptual foundation for what became the Architects Collaborative while they were classmates at Yale University, where they discussed forming "the World Collaborative," which would be an ideal office combining painting, sculpture, and architecture. Upon graduation, Norman Fletcher worked with John Harkness during the war at Skidmore, Owings & Merrill in New York, and later, John Harkness worked with Jean Fletcher for Saarinen and Swanson in Bloomfield Hills, Michigan the firm started by Eliel Saarinen. Jean Fletcher and Sarah Harkness had both studied at the Cambridge School of Architecture and Landscape Architecture. This group of friends were committed to forming a collaborative practice. To help them navigate the professional world and lend notability to the firm, they sought to add a senior practitioner. John Harkness pitched the idea of joining the Architects' Collaborative to Walter Gropius, who had asked Harkness to teach a master's class at Harvard. Walter Gropius agreed and became the eighth member of the group. Other principals came to include Richard Brooker, Alex Cvijanović, Herbert Gallagher, William Geddis, Roland Kluver, Peter Morton and H. Morse Payne, Jr. Design philosophy and organization The idea of "collaboration" was the basis of TAC. As described by McMillen, conforming to the ideal of anonymity helped bind the office together. It was carried out in that an entire group of architects have their input on a project, rather than putting an emphasis on individualism. There would be a "partner-in-charge", who would meet with clients and have the final decision of what goes into the design. Originally, each of the eight partners would hold weekly meetings on a Thursday to discuss their projects and be open to design input and ideas. However, as the firm grew larger there were many more people on a team and it was more difficult to consolidate into one group. Therefore, many
