Pierre Janneret is a swiss architect and designer, cousin and close collaborator of Le Corbusier. He graduated from the Ecole des Beaux Arts in Geneva. In 1921 he worked with Auguste and Gustave Perret in Paris before starting to work with Le Corbusier in 1922. His role was very important in all projects of this last collaboration; in 1926 they publish a manifesto entitled “Five Points Toward a New Architecture” which serves as a line of conduct to their architectural aesthetic. The construction which follows, the Villa Savoye (19281931), is a representation of their ideology.
The contribution of Jeanneret in association with Le Corbusier was significant. He often provided the first rough sketch plans which were gradually refined with Le Corbusier. He knew how to stimulate his cousin’s imagination by his own realism. He also played an important role in ensuring the continuity of the office, the coordination and control of the technical aspects. The attitude of Le Corbusier under Vichy will be a reason for the discontinuation of their collaboration.
