Brian Shields (1951–1997) was a Liverpool-born English painter.
 He is best known for painting industrial scenes of northern Britain.
 He acquired the nickname "Braaq" in his school days — on account of his artistic talent he was nicknamed "Braque" after the French artist Georges Braque.
Georges Braque ( ; ] ; 13 May 1882 – 31 August 1963) was a major 20th-century French painter, collagist, draughtsman, printmaker and sculptor.
 His most important contributions to the history of art were in his alliance with Fauvism from 1906, and the role he played in the development of Cubism.
 Braque’s work between 1908 and 1912 is closely associated with that of his colleague Pablo Picasso.
 Their respective Cubist works were indistinguishable for many years, yet the quiet nature of Braque was partially eclipsed by the fame and notoriety of Picasso.
John Erhart Kashdan (12 February 1917 - 22 February 2001) was an English painter, printmaker and teacher of Russian Jewish descent.
 He studied at the Royal Academy Schools and later exhibited in London and America before withdrawing from exhibiting around 1950 to focus on his teaching career.
 His work in the 1940s was influenced by Pablo Picasso, Juan Gris and Georges Braque.
 Post-war influences include Paul Klee and José Guadalupe Posada as well as contemporaries Robert Colquhoun and Robert MacBryde.
Concert is an oil on canvas still-life painting by Cubist painter Georges Braque, painted in 1937.
 It measures 28 × 35½ in.
 (71.12 × 90.17 cm).
 In comparison to earlier paintings by Braque, especially those of Analytical Cubism, it contains Surrealist inspired aspects, such as a more colorful palette, and a more representational rendering of the objects.
 "Concert" incorporates colors such as green and blue, as opposed to containing strictly neutral tones.
 However, "Concert" still incorporates many Cubist elements, such as the play on perspectives, fragmentation, and the inclusion of letters.
Katerina Wilczynski (1894-1978) was a 20th-century painter, printmaker and illustrator.
 She was born in Poland but spent a large part of her career in Britain and Italy.
 Wilczynski painted portraits and cityscapes throughout her career, but is best known as a landscape artist.
20th-century Western painting begins with the heritage of late-19th-century painters Vincent van Gogh, Paul Cézanne, Paul Gauguin, Georges Seurat and Henri de Toulouse-Lautrec, and others who were essential for the development of modern art.
 At the beginning of the 20th century, Henri Matisse and several other young artists including the pre-cubist Georges Braque, André Derain, Raoul Dufy and Maurice de Vlaminck revolutionized the Paris art world with "wild", multi-colored, expressive landscapes and figure paintings that the critics called Fauvism.
 Matisse's second version of "The Dance" signified a key point in his career and in the development of modern painting.
 It reflected Matisse's incipient fascination with primitive art: the intense warm color of the figures against the cool blue-green background and the rhythmical succession of the dancing nudes convey the feelings of emotional liberation and hedonism.
Hans Erni (February 21, 1909 – March 21, 2015) was a Swiss graphic designer, painter, illustrator, engraver and sculptor.
 Born in Lucerne, the third of eight siblings, to a cabin cruiser engineer, he studied art at the Académie Julian in Paris and later in Berlin, and admired artist such as Pablo Picasso and Georges Braque.
 He is known for having illustrated postage stamps, his lithographs for the Swiss Red Cross, his participation on the Olympic Committee as well as his activism.
 His 1939 works and first major public success was a mural titled Switzerland: "Vacation Land of the People" was commissioned and displayed for the national exhibition in Zürich.
 The Hans Erni Museum, situated in the grounds of the Swiss Museum of Transport in Lucerne, contains a large collection of artwork, he also designed ceramics and theatre costumes and sets.
 He did the art for Swiss bank notes, in the 1940s but, after the notes were already printed they were never published, because a member of the State Council of Lucerne criticized that Erni was deemed as a communist.
 However, Erni was never member of any political party.
 In 2004, he was awarded the honorary citizenship of the city of Lucerne.
 On 10 January 2009 he received the SwissAward for lifetime accomplishment.
 In his career, he realized about 300 posters and several murals (for the Red Cross, the IOC, the United Nations, ICAO, and many public and private enterprises).
 He illustrated about 200 books and created 90 Postage stamps and 25 medals.
Glebe House and "Glebe Gallery" are located just outside the town of Letterkenny near Churchill.
 The English portrait and landscape painter Derek Hill lived and worked there from 1954 until he presented the house and his art collection to the Irish state in 1981.
 Hill's former studio has been converted into a modern gallery with changing exhibitions while his art collection is shown in his former home together with European and oriental furniture and William Morris wallpapers and fabrics.
 The collection includes works by Pablo Picasso, Georges Braque, Louis le Brocquy, Graham Sutherland, Auguste Renoir, Jack Butler Yeats, Oskar Kokoshka, Patrick Swift and the native Tory Island painter, James Dixon.
L'Oiseau bleu (also known as The Blue Bird and Der Blaue Vogel) is a large oil painting created in 1912–1913 by the French artist and theorist Jean Metzinger (1883–1956); considered by Guillaume Apollinaire and André Salmon as a founder of Cubism, along with Georges Braque and Pablo Picasso.
 "L'Oiseau bleu", one of Metzinger's most recognizable and frequently referenced works, was first exhibited in Paris at the Salon des Indépendants in the spring of 1913 (n. 2087), several months after the publication of the first (and only) Cubist manifesto, "Du «Cubisme»", written by Jean Metzinger and Albert Gleizes (1912).
 It was subsequently exhibited at the 1913 in Berlin (titled "Der blaue Vogel", n. 287).
 Apollinaire described "L'Oiseau bleu" as a 'very brilliant painting' and 'his most important work to date'.
 "L'Oiseau bleu", acquired by the City of Paris in 1937, forms part of the permanent collection at the Musée d'Art Moderne de la Ville de Paris.
Sir William Rothenstein (29 January 1872 – 14 February 1945) was an English painter, printmaker, draughtsman, lecturer, and writer on art.
 Emerging during the early 1890s, Rothenstein continued to make art right up until his death in the mid-1940s.
 Though he covered many subjects – ranging from landscapes in France to representations of Jewish synagogues in London – he is perhaps best known for his work as a war artist in both world wars, his portraits, and his popular memoirs, written in the 1930s.
 More than two hundred of Rothenstein's portraits of famous people can be found in the National Portrait Gallery collection.
 The Tate Gallery also holds a large collection of his paintings, prints and drawings.
 Rothenstein served as Principal at the Royal College of Art from 1920 to 1935.
 He was knighted in 1931 for his services to art.
 In March 2015 'From Bradford to Benares: the Art of Sir William Rothenstein', the first major exhibition of Rothenstein's work for over forty years, opened at Bradford's Cartwright Hall Gallery, touring to the Ben Uri in London later that year.
