Answer by taking a quote from the following article:

Marc Zakharovich Chagall ( sh@-GAHL; born Moishe Zakharovich Shagal; 6 July [O.S. 24 June] 1887 - 28 March 1985) was a Russian-French artist of Belarusian Jewish origin. An early modernist, he was associated with several major artistic styles and created works in virtually every artistic format, including painting, book illustrations, stained glass, stage sets, ceramic, tapestries and fine art prints. Art critic Robert Hughes referred to Chagall as "the quintessential Jewish artist of the twentieth century" (though Chagall saw his work as "not the dream of one people but of all humanity"). According to art historian Michael J. Lewis, Chagall was considered to be "the last survivor of the first generation of European modernists".

In 1923, Chagall left Moscow to return to France. On his way he stopped in Berlin to recover the many pictures he had left there on exhibit ten years earlier, before the war began, but was unable to find or recover any of them. Nonetheless, after returning to Paris he again "rediscovered the free expansion and fulfillment which were so essential to him", writes Lewis. With all his early works now lost, he began trying to paint from his memories of his earliest years in Vitebsk with sketches and oil paintings. He formed a business relationship with French art dealer Ambroise Vollard. This inspired him to begin creating etchings for a series of illustrated books, including Gogol's Dead Souls, the Bible, and the La Fontaine's Fables. These illustrations would eventually come to represent his finest printmaking efforts. In 1924, he travelled to Brittany and painted La fenetre sur l'Ile-de-Brehat. By 1926 he had his first exhibition in the United States at the Reinhardt gallery of New York which included about 100 works, although he did not travel to the opening. He instead stayed in France, "painting ceaselessly", notes Baal-Teshuva. It was not until 1927 that Chagall made his name in the French art world, when art critic and historian Maurice Raynal awarded him a place in his book Modern French Painters. However, Raynal was still at a loss to accurately describe Chagall to his readers: Chagall interrogates life in the light of a refined, anxious, childlike sensibility, a slightly romantic temperament ... a blend of sadness and gaiety characteristic of a grave view of life. His imagination, his temperament, no doubt forbid a Latin severity of composition. During this period he traveled throughout France and the Cote d'Azur, where he enjoyed the landscapes, colorful vegetation, the blue Mediterranean Sea, and the mild weather. He made repeated trips to the countryside, taking his sketchbook. He also visited nearby countries and later wrote about the impressions some of those travels left on him: I should like to recall how advantageous my travels outside France have been for me in an artistic sense--in Holland or in Spain, Italy, Egypt, Palestine, or simply in the south of France. There, in the south, for the first time in my life, I saw that rich greenness--the like of which I had never seen in my own country. In Holland I thought I discovered that familiar and throbbing light, like the light between the late afternoon and dusk. In Italy I found that peace of the museums which the sunlight brought to life. In Spain I was happy to find the inspiration of a mystical, if sometimes cruel, past, to find the song of its sky and of its people. And in the East [Palestine] I found unexpectedly the Bible and a part of my very being. CANNOTANSWER
