Marcel Duchamp in the context of "Dadaist"

Conceptual art, also referred to as conceptualism, is art in which the concept(s) or idea(s) involved in the work are prioritized equally to or more than traditional aesthetic, technical, and material concerns. Some works of conceptual art may be constructed by anyone simply by following a set of written instructions. This method was fundamental to American artist Sol LeWitt's definition of conceptual art, one of the first to appear in print:

Tony Godfrey, author of Conceptual Art (Art & Ideas) (1998), asserts that conceptual art questions the nature of art, a notion that Joseph Kosuth elevated to a definition of art itself in his seminal, early manifesto of conceptual art, Art after Philosophy (1969). The notion that art should examine its own nature was already a potent aspect of the influential art critic Clement Greenberg's vision of Modern art during the 1950s. With the emergence of an exclusively language-based art in the 1960s, however, conceptual artists such as Art & Language, Joseph Kosuth (who became the American editor of Art-Language), and Lawrence Weiner began a far more radical interrogation of art than was previously possible (see below). One of the first and most important things they questioned was the common assumption that the role of the artist was to create special kinds of material objects.

Fountain is a readymade sculpture by Marcel Duchamp in 1917, consisting of a porcelain urinal signed "R. Mutt". In April 1917, an ordinary piece of plumbing chosen by Duchamp was submitted for the inaugural exhibition of the Society of Independent Artists, to be staged at the Grand Central Palace in New York. When explaining the purpose of his readymade sculpture, Duchamp stated they are "everyday objects raised to the dignity of a work of art by the artist's act of choice." In Duchamp's presentation, the urinal's orientation was altered from its usual positioning. Fountain was not rejected by the committee, since Society rules stated that all works would be accepted from artists who paid the fee, but the work was never placed in the show area. Following that removal, Fountain was photographed at Alfred Stieglitz's studio, and the photo published in the Dada journal The Blind Man. The original has been lost.

The work is regarded by art historians and theorists of the avant-garde as a major landmark in 20th-century art. Sixteen replicas were commissioned from Duchamp in the 1950s and 1960s and made to his approval. Some have suggested that the original work was by the female artist Elsa von Freytag-Loringhoven who had submitted it to Duchamp as a friend, but art historians maintain that Duchamp was solely responsible for Fountain's presentation.

In copyright law, a derivative work is an expressive creation that includes major copyrightable elements of a first, previously created original work (the underlying work). The derivative work becomes a second, separate work independent from the first. The transformation, modification or adaptation of the work must be substantial and bear its author's personality sufficiently to be original and thus protected by copyright. Translations, cinematic adaptations and musical arrangements are common types of derivative works.

Most countries' legal systems seek to protect both original and derivative works. They grant authors the right to impede or otherwise control their integrity and the author's commercial interests. Derivative works and their authors benefit in turn from the full protection of copyright without prejudicing the rights of the original work's author.

Surrealist cinema is a modernist approach to film theory, criticism, and production, with origins in Paris, France in the 1920s. The Surrealist movement used shocking, irrational, or absurd imagery and Freudian dream symbolism to challenge the traditional function of art to represent reality. Related to Dada cinema, Surrealist cinema is characterized by juxtapositions, the rejection of dramatic psychology, and a frequent use of shocking imagery. Philippe Soupault and André Breton’s 1920 book collaboration Les Champs magnétiques is often considered to be the first Surrealist work, but it was only once Breton had completed his Surrealist Manifesto in 1924 that ‘Surrealism drafted itself an official birth certificate.’

Surrealist films of the 1920s include René Clair's Entr'acte (1924), Fernand Léger's Ballet Mécanique (1924), Jean Renoir's La Fille de l'Eau (1924), Marcel Duchamp's Anemic Cinema (1926), Jean Epstein's Fall of the House of Usher (1928) (with Luis Buñuel assisting), Watson and Webber's Fall of the House of Usher (1928) and Germaine Dulac's The Seashell and the Clergyman (1928) (from a screenplay by Antonin Artaud). Other films include Un Chien Andalou (1929) and L'Âge D'Or (1930), both by Buñuel and Salvador Dalí; Buñuel went on to direct many more films, never denying his surrealist roots. Ingmar Bergman said "Buñuel nearly always made Buñuel films".

Dada (/ˈdɑːdɑː/) or Dadaism was an international art movement that developed in the context of the Great War and Futurism first established in Zürich, Switzerland, and later quickly spread to Berlin, Paris, New York City and a variety of artistic centers in Europe and Asia. The Dada movement's principles were first collected in Hugo Ball's Dada Manifesto in 1916. Ball is seen as the founder of the Dada movement. Key figures in the movement included Hugo Ball, Emmy Hennings, Jean Arp, Johannes Baader, Marcel Duchamp, Max Ernst, Elsa von Freytag-Loringhoven, George Grosz, Raoul Hausmann, John Heartfield, Hannah Höch, Richard Huelsenbeck, Francis Picabia, Man Ray, Hans Richter, Kurt Schwitters, Sophie Taeuber-Arp, Tristan Tzara, and Beatrice Wood, among others. The movement influenced later styles like the avant-garde and downtown music movements, and groups including Surrealism, nouveau réalisme, pop art, and Fluxus.

The Salon d'Automne (French: [salɔ̃ dotɔn]; English: Autumn Salon), or Société du Salon d'automne, is an art exhibition held annually in Paris. Since 2011, it is held on the Champs-Élysées, between the Grand Palais and the Petit Palais, in mid-October. The first Salon d'Automne was created in 1903 by Frantz Jourdain, with Hector Guimard, George Desvallières, Eugène Carrière, Félix Vallotton, Édouard Vuillard, Eugène Chigot and Maison Jansen.

Perceived as a reaction against the conservative policies of the official Paris Salon, this massive exhibition almost immediately became the showpiece of developments and innovations in 20th-century painting, drawing, sculpture, engraving, architecture and decorative arts. During the Salon's early years, established artists such as Pierre-Auguste Renoir threw their support behind the new exhibition and even Auguste Rodin displayed several works. Since its inception, works by artists such as Paul Cézanne, Henri Matisse, Paul Gauguin, Georges Rouault, André Derain, Albert Marquet, Jean Metzinger, Albert Gleizes and Marcel Duchamp have been shown. In addition to the 1903 inaugural exhibition, three other dates remain historically significant for the Salon d'Automne: 1905 bore witness to the birth of Fauvism; 1910 witnessed the launch of Cubism; and 1912 resulted in a xenophobic and anti-modernist quarrel in the National Assembly (France).

291 is the commonly known name for an internationally famous art gallery that was located in Midtown Manhattan at 291 Fifth Avenue in New York City from 1905 to 1917. Originally called the "Little Galleries of the Photo-Secession", the gallery was established and managed by photographer Alfred Stieglitz.

The gallery is recognized for two achievements: First, its exhibitions helped bring art photography to the same stature in America as painting and sculpture. Pioneering artistic photographers such as Stieglitz, Edward Steichen, Alvin Langdon Coburn, Gertrude Käsebier and Clarence H. White all gained critical recognition through exhibitions at 291. Equally important, Stieglitz used this space to introduce to the United States some of the most avant-garde European artists of the time, including Henri Matisse, Auguste Rodin, Henri Rousseau, Paul Cézanne, Pablo Picasso, Constantin Brâncuși, Marcel Duchamp, and the Dadaist Francis Picabia.

L.H.O.O.Q. (French pronunciation: [ɛl aʃ o o ky]) is a work of art by Marcel Duchamp. First conceived in 1919, the work is one of what Duchamp referred to as readymades, or more specifically a rectified ready-made. The readymade involves taking mundane, often utilitarian objects not generally considered to be art and transforming them, by adding to them, changing them, or (as in the case of his work Fountain) simply renaming and reorienting them and placing them in an appropriate setting. In L.H.O.O.Q. the found object (objet trouvé) is a cheap postcard reproduction of Leonardo da Vinci's early 16th-century painting Mona Lisa onto which Duchamp drew a moustache and beard in pencil and appended the title.
