LC/PJ-SI-41-A Advocate Chair by Pierre Jeanneret & Le Corbusier, 1950s

Born in Geneva in 1896, Swiss painter, architect, and designer Pierre Jeanneret studied architecture at the École des Beaux-Arts. After graduating in 1921, he worked in the Parisian architectural office of the Perret brothers, pioneers in the use of reinforced concrete. By 1923, he had set up an architectural practice in Paris with his cousin, Le Corbusier (1887-1965). The two worked side-by-side throughout their prolific careers, and Jeanneret's contribution to the partnership has become increasingly recognized. Their pivotal, 1926 manifesto, Five Points Towards a New Architecture, is considered to be a pillar of modernist thought and the intellectual foundation of their legendary work. Both architects were members of the Union des Artistes Modernes (UAM). Around the years of World War II, the partnership between Jeanneret and his cousin was interrupted; Jeanneret joined the French resistance, while Le Corbusier did not.

Between 1927 to 1940, Jeanneret and Le Corbusier collaborated with French designer Charlotte Perriand (1903-1999). Together the group created a number of now-iconic furniture designs, which were characterized by minimalist, geometric forms fabricated in industrial materials like tubular steel. Important designs that emerged from this collaboration include the LC4 Chaise Lounge (1928) and the Fauteuil Grand Confort seating collection (1928). Both designs were put into production by Thonet in 1930 and by Cassina in 1965.

After World War II, Jeanneret and Perriand teamed up with French designer Jean Prouvé to develop pre-fab housing concepts, including the town planning of Puteaux, France.

One of Jeanneret’s most enduring solo works is his Scissor Chair, which was designed in 1947 and manufactured by Knoll between 1948 and 1966. It features a simple, maple wood structure hinged together by circular brass struts and topped with two upholstered cushions.

In 1950, Le Corbusier suggested reforming their partnership to execute the master plan for Chandigarh, the capital of the Indian state of Punjab. Jeanneret lived on location and presided over the project. He assimilated the Indian building tradition with the architectural and technical solutions he formulated with his cousin. He stayed in Chandigarh for fifteen years, and the city evolved into a landmark of modernist architecture. Many of Jeanneret's most sought-after furniture designs were created for office interiors in Chandigarh.

Jeanneret died in Lausanne in 1967; in accordance with his wishes, his ashes were scattered on the Sukhna Lake in Chandigarh, India.

Born in Switzerland in 1887 as Charles-Édouard Jeanneret, Le Corbusier was an architect, urban planner, painter, writer, designer, and theorist who lived and worked primarily in France. In 1900, he began to study at the École d'Art in La Chaux-de-Fonds, Switzerland, as an engraver and goldsmith, expanding his studies in 1904 to include architecture. Among his influential early teachers were Auguste Perret, Jose Hoffman, and architect Peter Behrens. During World War I, Le Corbusier taught at his old school in La Chaux-de-Fonds. After the war, he returned to Paris and worked on concrete structures for the government while focusing most of his energy on painting.

In 1919, Le Corbusier and painter Amédée Ozenfant—cofounders of the Purism movement—launched the art magazine L’Esprit Nouveau (the Le Corbusier pseudonym was officially adopted in its first issue). The magazine presented Le Corbusier’s ideas on modern architecture, which were based on a philosophy of harmony and proportion. In 1922, he and his cousin Pierre Jeanneret opened a studio in Paris, a partnership that lasted until 1940. The pair began to experiment with furniture design after architect Charlotte Perriand joined the studio in 1928. In his design, architecture, and artwork, Le Corbusier embraced elemental geometric forms. In 1943, he developed Modulor, a system of proportions based on the male figure and the golden ratio, which was used to determine the proportions of units in architecture and technology. This also served as the basis for his furniture design.

After World War II, Le Corbusier sought efficient ways to house large numbers of people in response to the housing crisis. His most notable housing unit was the Unité d'Habitation of Marseilles (1946–52). He was also a founding member of the Congrès International d'Architecture Moderne (CIAM). During the 1950s, he was presented the unique opportunity to translate his vision on a large scale with the construction of the newly founded capital city of Chandigarh, India.

A leading 20^th-century modern architect, Le Corbusier pioneered the International style, working primarily with steel and reinforced concrete. His buildings were constructed across central Europe, India, and Russia, and one each in North and South America. Arguably, his most notable works are the Weissenhof Settlement in Stuttgart (1927) and Villa Savoye (1929–31). In 1961, he was awarded the Frank P. Brown Medal and the AIA Gold Medal. In 1964, Milan’s Cassina S.p.A. acquired exclusive worldwide rights to manufacture his furniture designs.

Le Corbusier died in August 1965.
