Question: Which American novelist, who moved to Paris in 1903, has a long-time friend who commissioned Le Corbusier to design an innovative cubist home?

Context paragraphs:
William Edwards Cook: William Edwards Cook (August 31, 1881 – November 10, 1959) was an American-born expatriate artist, architectural patron, and long-time friend of American writer Gertrude Stein.  Following his 1903 departure from the U.S., Cook resided in Paris, Rome, Russia, and on the island of Majorca, in the Balearic Islands off the eastern coast of Spain.  Today he is chiefly remembered not for his artistic achievements, but because, during World War I, he taught Stein to drive an automobile so that she could contribute to the French war effort, and because, in 1926, he commissioned the Swiss architect Le Corbusier (whose career was at an early stage) to design an innovative cubist home, on the outskirts of Paris, now called Maison Cook or Villa Cook.

Le Corbusier in the USSR: Le Corbusier had a short relationship with the Soviet Union, starting with his first trip to Moscow in 1928, and ending with the rejection of his proposal for the Palace of the Soviets in 1932.  Nevertheless, the short-lived relationship had consequences that went beyond Le Corbusier’s time in the USSR.  Before his trip to Moscow, Le Corbusier was already an influential figure within the Soviet field of architecture.  In 1922, Moisei Ginzburg, founder of the Constructivist movement, published materials from Le Corbusier’s “Towards a New Architecture,” and in 1924 published his own book, similar to Le Corbusier’s, titled "Style and Epoch", which became to a central text to the Constructivist movement.  Likewise, Corbusier’s projects were frequently published and analyzed as examples for the young generation of Soviet architects to use as inspiration.  When Le Corbusier died in 1965, the official newspaper of the Soviet Union, Pravda, stated in its obituary, “Modern architecture has lost its greatest master.”  This statement suggests the importance of Le Corbusier’s architecture and urbanism in the Soviet Union.

Pavillon Le Corbusier: The Pavillon Le Corbusier is a Swiss art museum in Zürich-Seefeld at Zürichhorn dedicated to the work of the Swiss architect Le Corbusier.  In 1960 Heidi Weber had the vision to establish a museum designed by Le Corbusier – this building should exhibit his works of art in an ideal environment created by the architect himself in the then Centre Le Corbusier or Heidi Weber Museum.  In April 2014 the building and museum went over to the city of Zürich, and was renamed in May 2016.

Poème électronique: Poème électronique (English Translation: "Electronic Poem") is an 8-minute piece of electronic music by composer Edgard Varèse, written for the Philips Pavilion at the 1958 Brussels World’s Fair.  The Philips corporation commissioned Le Corbusier to design the pavilion, which was intended as a showcase of their engineering progress.  Le Corbusier came up with the title "Poème électronique", saying he wanted to create a "poem in a bottle".  Varèse composed the piece with the intention of creating a liberation between sounds and as a result uses noises not usually considered "musical" throughout the piece.

Gertrude Stein: Gertrude Stein (February 3, 1874 – July 27, 1946) was an American novelist, poet, playwright, and art collector.  Born in the Allegheny West neighborhood of Pittsburgh, Pennsylvania, and raised in Oakland, California, Stein moved to Paris in 1903, and made France her home for the remainder of her life.  She hosted a Paris salon, where the leading figures of modernism in literature and art, such as Pablo Picasso, Ernest Hemingway, F. Scott Fitzgerald, Sinclair Lewis, Ezra Pound, and Henri Matisse, would meet.

Carpenter Center for the Visual Arts: The Carpenter Center for the Visual Arts at Harvard University, in Cambridge, Massachusetts is the only building actually designed by Le Corbusier in the United States, and one of only two in the Americas (the other is the Curutchet House in La Plata, Argentina).  Le Corbusier designed it with the collaboration of Chilean architect Guillermo Jullian de la Fuente at his 35 rue de Sèvres studio; the on-site preparation of the construction plans was handled by the office of Josep Lluís Sert, then dean of the Harvard Graduate School of Design.  He had formerly worked in Le Corbusier's atelier and had been instrumental in winning him the commission.  The building was completed in 1962.

Cabanon de vacances: The Cabanon de vacances is a vacation home designed and built by noted architect Le Corbusier in 1951.  It is the only place the architect Le Corbusier built for himself which he used for vacation.  In July 2016, the home and several other works by Le Corbusier were inscribed as UNESCO World Heritage Sites.

Guillermo Jullian de la Fuente: Guillermo Jullian de la Fuente was a Chilean architect and painter (1931 in Valparaíso, Chile – 2008 in Santiago, Chile).  After finishing his studies of architecture at the Catholic University of Valparaiso, Jullian left his country for Europe, with the declared desire to work with Le Corbusier.  Together with his wife, he visited the Swiss architect's works throughout Europe, before settling in Paris in 1958.  There, he wrote a letter to Le Corbusier where he told him about Valparaíso and he declared his admiration for his work, asking him for work at his atelier.  After a short exchange of letters, Jullian started working at the "rue de Sèvres" atelier in 1959, where he would stay until his master's death in 1965.  After Le Corbusier fired all his previous collaborators, Jullian was his only employee for six months, until others started to arrive there.  As "chef de bureau" at the "atelier", Jullian collaborated in such landmark projects as Harvard University’s Carpenter Center, the Knowledge Museum at Chandigargh, the Olivetti Laboratories, the Baghdad Stadium, the French embassy in Brasilia, and the Venice Hospital.  The latter project played an important role in the Team 10 discourse and is one of the clearest examples of mat-building typology and of the structuralist thinking in architecture.  In some of these works, like the Olivetti Laboratories, the Carpenter Center and the Venice Hospital, Jullian's participation was more relevant than that of a simple collaborator, and he has been identified as a co-author.

Villa Meyer: Villa Meyer (1925–1926) is an unbuilt project which was supposed to be built in Neuilly-sur-Seine, in downtown Paris.  Four designs were created for this house by Swiss architect Le Corbusier, but it was never built.  This is the first project into which Le Corbusier incorporated "free plan" and "free facade" into his design.  These ideas later become two of Corbusier's famous Five Points of Architecture.  Domino Frame is also an outcome of this experimental design, which became the dominant design concept of Corbusier's later works.

Le Corbusier's Furniture: Le Corbusier's Furniture is a classic furniture line created by Le Corbusier.  The line was introduced in 1928 at the Salon d‘Autumne in Paris by Le Corbusier and his team of designers.
