Born in Geneva in 1896, he ranks among the most important figures in the history of architecture and design. After his studies at the École des Beaux-Arts in his hometown, his career began to take shape at the studio of the Perret brothers, by whom he was strongly infused. In 1922 he opened his first studio together with his famous cousin Le Corbusier, with whom he carried out major projects throughout most of his life. In 1951 the two cousins created the majestic architectural Capitol Complex in the Indian city of Chandigharh, where in this project Jeannert was given the task of designing the building's interior and furnishings. The furniture made for this project aroused interest in Cassina, which decided to include Pierre Jeannert among the great architects belonging to the Cassina I Maestri Collection and creating a collection of furniture in his honor.
