Paul Gauguin in the context of "Post-Impressionism"

Modern art includes artistic work produced during the period extending roughly from the 1860s to the 1970s, and denotes the styles and philosophies of the art produced during that era. The term is usually associated with art in which the traditions of the past have been thrown aside in a spirit of experimentation. Modern artists experimented with new ways of seeing and with fresh ideas about the nature of materials and functions of art. A tendency away from the narrative, which was characteristic of the traditional arts, toward abstraction is characteristic of much modern art. More recent artistic production is often called contemporary art or Postmodern art.

Modern art begins with the post-impressionist painters like Vincent van Gogh, Paul Cézanne, Paul Gauguin, Georges Seurat and Henri de Toulouse-Lautrec. These artists were essential to modern art's development. At the beginning of the 20th century Henri Matisse and several other young artists including the pre-cubists Georges Braque, André Derain, Raoul Dufy, Jean Metzinger 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 two versions of The Dance signified a key point in his career and 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.

Post-Impressionism (also spelled Postimpressionism) was a predominantly French art movement which developed roughly between 1886 and 1905, from the last Impressionist exhibition to the birth of Fauvism. Post-Impressionism emerged as a reaction against Impressionists' concern for the naturalistic depiction of light and colour. Its broad emphasis on abstract qualities or symbolic content means Post-Impressionism encompasses Les Nabis, Neo-Impressionism, Symbolism, Cloisonnism, the Pont-Aven School, and Synthetism, along with some later Impressionists' work. The movement's principal artists were Paul Cézanne (known as the father of Post-Impressionism), Paul Gauguin, Vincent van Gogh and Georges Seurat.

The term Post-Impressionism was first used by art critic Roger Fry in 1906. Critic Frank Rutter in a review of the Salon d'Automne published in Art News, 15 October 1910, described Othon Friesz as a "post-impressionist leader"; there was also an advert for the show The Post-Impressionists of France. Three weeks later, Roger Fry used the term again when he organised the 1910 exhibition Manet and the Post-Impressionists, defining it as the development of French art since Édouard Manet.

The Letters of Vincent van Gogh is a collection of 903 surviving letters written (820) or received (83) by Vincent van Gogh. More than 650 of these were from Vincent to his brother Theo. The collection also includes letters van Gogh wrote to his sister Wil and other relatives, as well as between artists such as Paul Gauguin, Anthon van Rappard, and Émile Bernard.

Johanna van Gogh-Bonger, the wife of Vincent's brother Theo, spent many years after her husband's death in 1891 compiling the letters, which were first published in 1914. Arnold Pomerans, editor of a 1966 selection of the letters, wrote that Theo "was the kind of man who saved even the smallest scrap of paper", and it is to this trait that the public owes the 663 letters from Vincent.

Lizzie Plummer Bliss (April 11, 1864 – March 12, 1931), known as Lillie P. Bliss, was an American art collector and patron. At the beginning of the 20th century, she was one of the leading collectors of modern art in New York. One of the lenders to the landmark Armory Show in 1913, she also contributed to other exhibitions concerned with raising public awareness of modern art. In 1929, she played an essential role in the founding of the Museum of Modern Art. After her death, 150 works of art from her collection served as a foundation to the museum and formed the basis of the in-house collection. These included works by artists such as Paul Cézanne, Georges Seurat, Paul Gauguin, Henri Matisse, Pablo Picasso and Amedeo Modigliani.

Mary Quinn Sullivan (November 24, 1877 – December 5, 1939), born Mary Josephine Quinn, was a pioneering collector of European and American modern and contemporary art and gallerist, and a founding trustee of the Museum of Modern Art, which opened in rented space in New York City in November 1929. She also led a small group of Indianapolis, Indiana, art patrons who called themselves the Gamboliers and between 1928 and 1934 selected artworks of for the group that brought some of the first modern and contemporary works to the collections of the John Herron Art Institute, which later became the Indianapolis Museum of Art.

Mary and Cornelius J. Sullivan, her husband, amassed a significant private collection of art during the 1920s and 1930s that included Modigliani's Sculptured Head of a Woman, Paul Cézanne's Madame Cézanne, Georges Rouault's Crucifixion, and a Hepplewhite desk that once belonged to Edgar Degas, as well as works by Pierre-Auguste Renoir, Paul Gauguin, Henri de Toulouse-Lautrec, Vincent van Gogh, Pierre Bonnard, Pablo Picasso, and others.

Jacob Abraham Camille Pissarro (/pɪˈsɑːroʊ/ piss-AR-oh; French: [kamij pisaʁo]; 10 July 1830 – 13 November 1903) was a Danish-French Impressionist and Neo-Impressionist painter born on the island of St Thomas (now in the US Virgin Islands, but then in the Danish West Indies). His importance resides in his contributions to both Impressionism and Post-Impressionism. Pissarro studied from great forerunners, including Gustave Courbet and Jean-Baptiste-Camille Corot. He later studied and worked alongside Georges Seurat and Paul Signac when he took on the Neo-Impressionist style at the age of 54.

In 1873 he helped establish a collective society of fifteen aspiring artists, becoming the "pivotal" figure in holding the group together and encouraging the other members. Art historian John Rewald called Pissarro the "dean of the Impressionist painters", not only because he was the oldest of the group, but also "by virtue of his wisdom and his balanced, kind, and warmhearted personality". Paul Cézanne said "he was a father for me. A man to consult and a little like the good Lord", and he was also one of Paul Gauguin's masters. Pierre-Auguste Renoir referred to his work as "revolutionary", through his artistic portrayals of the "common man", as Pissarro insisted on painting individuals in natural settings without "artifice or grandeur".

Comte Henri Marie Raymond de Toulouse-Lautrec-Montfa (24 November 1864 – 9 September 1901), known as Toulouse-Lautrec (French: [tuluz lotʁɛk]), was a French painter, printmaker, draughtsman, caricaturist, and illustrator. His immersion in the colourful and theatrical life of Paris in the late 19th century allowed him to produce popular works of art from decadent affairs.

Born into the aristocracy, Toulouse-Lautrec broke both his legs during adolescence, leaving him with a stunted appearance. In later life, he developed an affinity for brothels and prostitutes that directed the subject matter for many of his works, which record details of the late-19th-century bohemian lifestyle in Paris. He is among the painters described as Post-Impressionists, with Paul Cézanne, Vincent van Gogh, Paul Gauguin, and Georges Seurat also commonly considered as belonging in this loose group.

The Nabis (French: les nabis, French pronunciation: [le nabi]) were a group of young French artists active in Paris from 1888 until 1900, who played a large part in the transition from Impressionism and academic art to abstract art, symbolism and the other early movements of modernism. The members included Pierre Bonnard, Maurice Denis, Paul Ranson, Édouard Vuillard, Ker-Xavier Roussel, Félix Vallotton, Paul Sérusier and Auguste Cazalis. Most were students at the Académie Julian in Paris in the late 1880s. The artists shared a common admiration for Paul Gauguin and Paul Cézanne and a determination to renew the art of painting, but varied greatly in their individual styles. They believed that a work of art was not a depiction of nature, but a synthesis of metaphors and symbols created by the artist. In 1900, the artists held their final exhibition and went their separate ways.
