Team 10 was a group of indivuduals came together rather than a strict organized group, the concept of membership or movement did not exist. They organized meetings between 1955 and 1981, it was then when they discussed about who was to be invited. Still, there was a core group which was different from invited members. They were the most active and longest-involved participants in Team 10, namely Jaap Bakema, Georges Candilis, Giancarlo De Carlo, Aldo van Eyck, Alison and Peter Smithson and Shadrach Woods. The core group started meeting first within the context of CIAM, which had become a venue for new generation architects after the war. Candilis had already been taking part in the CIAM meetings since the congress in Athens, 1933, while Bakema and Van Eyck had been involved in the discussions on the future of modern architecture since the ‘reunion’ congress in Bridgwater, 1947. Alison and Peter Smithson attended the congress in Hoddesdon in 1951 to hear Le Corbusier, and it was there that they met, among others, Candilis, Bakema and Van Eyck. They were the ones who would form part of the core of Team 10 after the dissolution of CIAM, as would Shadrach Woods and Giancarlo De Carlo.
Between 1953-81 was the time when the most intensive interaction occured betwen core participants. All of them participate the CIAM in 1953 except for De Carlo, he participate in 1955. The last official meeting of the Team 10 was in 1977, but in retrospect the core participants identify the demise of Bakema in 1981 as marking the end of Team 10. After loss of Bakema and the dispute between Van Eyk and Smithsons the core group became disintegrated.
They do not have any theory, there was only one manifesto, which was The Doorn Manifesto of 1954. Even this one manifesto was moreover a subject of dispute between the Dutch and English younger members of CIAM. Mention may be made of two other brief public statements which were sent into the world in 1961 in the aftermath of the dissolution of CIAM – the ‘Paris Statement’ and ‘The Aim of Team 10’. They called these programme new architecture. It could be argued that the only ‘product’ of Team 10 as a group was its meetings, at which the participants put up their projects on the wall, and exposed themselves to the ruthless analysis and fierce criticism of their peers.
