Question:
Chicago is an American rock band formed in 1967 in Chicago, Illinois as The Chicago Transit Authority before shortening the name in 1970. The self-described "rock and roll band with horns" began as a politically charged, sometimes experimental, rock band and later moved to a predominantly softer sound, generating several hit ballads. The group had a steady stream of hits throughout the 1970s and 1980s. Since at least 2008, Billboard has shown Chicago to be the "greatest of all time" American band in singles chart success, and since 2015, the "greatest of all time" American band in album chart success as well.
The year 1978 began with a split with Guercio. Chicago had recorded its last five studio albums Chicago VI, VII, VIII, X, and XI, and had made two television specials at Guercio's Caribou Ranch. In later years, band members would cite Guercio's purchase of Caribou Ranch, more particularly their realization that Guercio had enough money to purchase Caribou Ranch, as a contributing factor to their disillusionment with him as a producer. They felt he had taken advantage of them financially. Then on January 23 of that same year, Kath died of an accidental, self-inflicted gunshot wound from a gun he thought was unloaded. Doc Severinsen, who was the bandleader for The Tonight Show Starring Johnny Carson at the time and a friend of the group, visited them after Kath's funeral and encouraged them to continue. According to writer Jim Jerome, the visit "snapped them back" and helped them make the decision to carry on. After auditioning over 30 potential replacements for Kath, Chicago decided upon guitarist and singer-songwriter Donnie Dacus. While filming for the musical Hair, he joined the band in April 1978 just in time for the Hot Streets album. Its energetic lead-off single, "Alive Again", brought Chicago back to the Top 15; Pankow wrote it "originally as a love song but ultimately as recognition of Kath's guiding spirit shining down from above." The 1978 album Hot Streets was produced by Phil Ramone. It was Chicago's first album with a title rather than a number; and was the band's first LP to have a picture of the band (shot by photographer Norman Seeff) featured prominently on the cover (with the ubiquitous logo downsized). These two moves were seen by many as indications that the band had changed following Kath's death. To a degree, the band returned to the old naming scheme on its subsequent releases, although most titles would now bear Arabic numerals rather than Roman numerals. Hot Streets, the band's 12th album, peaked at No. 12 on the Billboard charts; it was Chicago's first release since their debut to fail to make the Top 10. The release also marked a move somewhat away from the jazz-rock direction favored by Kath and towards more pop songs and ballads. Dacus stayed with the band through the 1979 album Chicago 13, and is also featured in a promotional video on the DVD included in the Rhino Records Chicago box set from 2003. Again produced by Ramone, it was the group's first studio album not to contain a Top 40 hit. Dacus departed from the band shortly after the album's release.

Question:
Charles-Edouard Jeanneret, known as Le Corbusier (French: [l@ koRby'zje]; 6 October 1887 - 27 August 1965), was a Swiss-French architect, designer, painter, urban planner, writer, and one of the pioneers of what is now called modern architecture. He was born in Switzerland and became a French citizen in 1930. His career spanned five decades and he designed buildings in Europe, Japan, India, and North and South America.
Le Corbusier moved to Paris definitively in 1917 and began his own architectural practice with his cousin, Pierre Jeanneret (1896-1967), a partnership that would last until the 1950s, with an interruption in the World War II years In 1918, Le Corbusier met the Cubist painter Amedee Ozenfant, in whom he recognised a kindred spirit. Ozenfant encouraged him to paint, and the two began a period of collaboration. Rejecting Cubism as irrational and "romantic", the pair jointly published their manifesto, Apres le cubisme and established a new artistic movement, Purism. Ozenfant and Le Corbusier began writing for a new journal, L'Esprit Nouveau, and promoted with energy and imagination his ideas of architecture. In the first issue of the journal, in 1920, Charles-Edouard Jeanneret adopted Le Corbusier (an altered form of his maternal grandfather's name, Lecorbesier) as a pseudonym, reflecting his belief that anyone could reinvent themselves. Adopting a single name to identify oneself was in vogue by artists in many fields during that era, especially in Paris. Between 1918 and 1922, Le Corbusier did not build anything, concentrating his efforts on Purist theory and painting. In 1922, he and his cousin Pierre Jeanneret opened a studio in Paris at 35 rue de Sevres. His theoretical studies soon advanced into several different single-family house models. Among these was the Maison "Citrohan", a pun on the name of the French Citroen automaker, for the modern industrial methods and materials Le Corbusier advocated using for the house. Here, Le Corbusier proposed a three-floor structure, with a double-height living room, bedrooms on the second floor, and a kitchen on the third floor. The roof would be occupied by a sun terrace. On the exterior Le Corbusier installed a stairway to provide second-floor access from ground level. Here, as in other projects from this period, he also designed the facades to include large uninterrupted banks of windows. The house used a rectangular plan, with exterior walls that were not filled by windows but left as white, stuccoed spaces. Le Corbusier and Jeanneret left the interior aesthetically spare, with any movable furniture made of tubular metal frames. Light fixtures usually comprised single, bare bulbs. Interior walls also were left white.
