Problem: Jean Desire Gustave Courbet (French: [gystav kuRbe]; 10 June 1819 - 31 December 1877) was a French painter who led the Realism movement in 19th-century French painting. Committed to painting only what he could see, he rejected academic convention and the Romanticism of the previous generation of visual artists. His independence set an example that was important to later artists, such as the Impressionists and the Cubists. Courbet occupies an important place in 19th-century French painting as an innovator and as an artist willing to make bold social statements through his work.

In the Salon of 1857 Courbet showed six paintings. These included Young Ladies on the Banks of the Seine (Summer), depicting two prostitutes under a tree, as well as the first of many hunting scenes Courbet was to paint during the remainder of his life: Hind at Bay in the Snow and The Quarry. Young Ladies on the Banks of the Seine, painted in 1856, provoked a scandal. Art critics accustomed to conventional, "timeless" nude women in landscapes were shocked by Courbet's depiction of modern women casually displaying their undergarments. By exhibiting sensational works alongside hunting scenes, of the sort that had brought popular success to the English painter Edwin Landseer, Courbet guaranteed himself "both notoriety and sales". During the 1860s, Courbet painted a series of increasingly erotic works such as Femme nue couchee. This culminated in The Origin of the World (L'Origine du monde) (1866), which depicts female genitalia and was not publicly exhibited until 1988, and Sleep (1866), featuring two women in bed. The latter painting became the subject of a police report when it was exhibited by a picture dealer in 1872. Until about 1861, Napoleon's regime had exhibited authoritarian characteristics, using press censorship to prevent the spread of opposition, manipulating elections, and depriving Parliament the right to free debate or any real power. In the 1860s, however, Napoleon III made more concessions to placate his liberal opponents. This change began by allowing free debates in Parliament and public reports of parliamentary debates. Press censorship, too, was relaxed and culminated in the appointment of the Liberal Emile Ollivier, previously a leader of the opposition to Napoleon's regime, as the de facto Prime Minister in 1870. As a sign of appeasement to the Liberals who admired Courbet, Napoleon III nominated him to the Legion of Honour in 1870. His refusal of the cross of the Legion of Honour angered those in power but made him immensely popular with those who opposed the prevailing regime.

was his work exhibited publicly?

Problem: The Clark Sisters are an American gospel vocal group consisting of five sisters: Jacky Clark Chisholm (b. 1948), Denise Clark Bradford (b. 1953), Elbernita "Twinkie" Clark-Terrell (b. 1954), Dorinda Clark-Cole (b. 1957), and Karen Clark Sheard (b. 1960). The Clark Sisters are the daughters of gospel musician and choral director Mattie Moss Clark. They are credited for helping to bring gospel music to the mainstream and are considered as pioneers of contemporary gospel.

The Clark Sisters were born and raised in Detroit, Michigan. They each began singing at an early age, and by the late 1960s they were all performing together in church services, usually singing songs written and arranged by their mother. A few years later, Dr. Mattie Moss Clark turned over control of the group to Twinkie, who would then go on to write, arrange, conduct, and produce all of the Clark Sisters' recordings. In 1973, the sisters recorded their first album, Jesus Has A Lot To Give, on their uncle's local label Billesse Records. The following year, Dr. Mattie Moss Clark Presents The Clark Sisters was released and people around Detroit began to take notice of the group. The Clark Sisters signed to Sound of Gospel Records in 1974. Under this association, the group released albums such as Unworthy, Count It All Joy, and He Gave Me Nothing to Lose. It was not until the early 1980s that The Clark Sisters began to become more widely known. Their popularity soared with the release of the live recording Is My Living In Vain. The first live recording by The Clark Sisters spent an entire year at number one on Billboard's Gospel Music chart. Opening with the bluesy title track, each sister vocally declares that their dedication to Christ is not a useless effort. The innovative "Hi ya" was funky enough to find its way into a Tonex produced track over two decades later. Karen Clark's lead on "Speak Lord" expresses deep faith while the call to worship is raised on "Now Is The Time". Another hit from this release, "Expect Your Miracle", is still a staple in black churches across the country. Their next release You Brought the Sunshine would prove to be a monster hit via the title track. Reminiscent of Stevie Wonder's "Master Blaster (Jammin')," the song became a hit in church houses and on dance floors, including New York's Studio 54. "Sunshine" was picked up from its original independent gospel record label Sounds of Gospel and distributed by both Westbound Records and Elektra Records. In 1983, the song peaked at #16 on the Black Singles chart, #27 on the Club Play Charts, and #80 on the Hot R&B Charts driving the album to Gold sales. This album continues to display Twinkie's signature blend of scripture with unprecedented vocal and musical arrangements on biblically based songs like "Psalms 31." The album's other songs include the sincere prayer found within the lyrics of both "Center of Thy Will" and "Endow Me," featuring a young but already vocally mature Karen, as well as "Overdose of the Holy Ghost", showcasing Dorinda's vocal dexterity. The disco-inspired "He Keeps Me Company" is noted for its bubbly syncopation. The sisters delivered another progressive effort in 1982, Sincerely, which included "Name It And Claim It" and the politically charged "World." Though its success was overshadowed by the previous hit "You Brought The Sunshine", the album received a Grammy nomination.
