Modern sculpture
Modern sculpture is generally considered to have begun with the work of Auguste Rodin, who is seen as the progenitor of modern sculpture. While Rodin did not set out to rebel against the past, he created a new way of building his works. He "dissolved the hard outline of contemporary Neo-Greek academicism, and thereby created a vital synthesis of opacity and transparency, volume and void". Along with a few other artists in the late 19th century who experimented with new artistic visions in sculpture like Edgar Degas and Paul Gauguin, Rodin invented a radical new approach in  the creation of sculpture. Modern sculpture, along with all modern art, "arose as part of Western society's attempt to come to terms with the urban, industrial and secular society that emerged during the nineteenth century". Modernist sculpture movements include Art Nouveau, Cubism, Geometric abstraction, De Stijl, Suprematism, Constructivism, Dadaism, Surrealism, Futurism, Formalism Abstract expressionism, Pop-Art, Minimalism, Postminimalism, Land art, Conceptual art, and Installation art among others. Modernism. The modern sculpture movement can be said to begin at the Rodin exhibit at the Universal Exhibition held in Paris in 1900. At this event Rodin showed his Burghers of Calais , Balzac, Victor Hugo statues, and the exhibition included the first public showing of his Gates of Hell which included The Thinker. Cubist sculpture, in the early 20th century, was a style that developed in parallel with cubist painting, and the formal experiments of Georges Braque and Pablo Picasso. Beginning around 1909 and evolving through the early 1920s cubist artists developed new means of constructing works of art using collage, sculptural assemblage using disparate materials and traditional sculpture making from plaster and clay molds. Some sources name Picasso's 1909 bronze "Head of a Woman" as the first cubist sculpture. Artists  like Raymond Duchamp-Villon (1876-1918), whose career was cut short by his death in military service, and Alexander Archipenko, who'd arrived in Paris in 1908 and whose 1912 "Walking Woman" were very quick to follow Braque and Picasso's lead. Joseph Csaky, a sculptor from Hungary, exhibited his first cubist sculptures in Paris in 1911. Duchamp-Villon, Jacques Lipchitz, Henri Laurens and Ossip Zadkine and others joined the earlier cubist sculptors. In the early 20th century, during his period of cubist innovation, Pablo Picasso revolutionized the art of sculpture when he began creating his "constructions" fashioned by combining  disparate objects and materials into one constructed piece of sculpture; Picasso reinvented the art of sculpture with his innovative use of constructing a work in three dimensions with disparate material, the sculptural equivalent of the collage in two-dimensional art. Just as collage was a radical development in two-dimensional art; so was "construction" a radical development in three-dimensional sculpture. The advent of Surrealism led to things occasionally being described as "sculpture" that would not have been so previously, such as "involuntary sculpture" in several senses, including coulage. In later years Picasso became a prolific potter, leading, with interest  in historic pottery from around the world, to a revival of ceramic art, with figures such as George E. Ohr and subsequently Peter Voulkos, Kenneth Price, and Robert Arneson. Marcel Duchamp originated the use of the "found object" (French: "objet trouvé") or "readymade" with pieces such as Fountain (1917). Similarly, the work of Constantin Brâncuși at the beginning of the century paved the way for later abstract sculpture. In revolt against the naturalism of Rodin and his late 19th-century contemporaries, Brâncuși distilled subjects down to their essences as illustrated by the elegantly refined forms of his "Bird in Space  series (1924). These elegantly refined forms became synonymous with 20th-century sculpture. In 1927, Brâncuși won a lawsuit against the U.S. customs authorities who attempted to value his sculpture as raw metal. The suit led to legal changes permitting the importation of abstract art free of duty. Brâncuși's impact, with his vocabulary of reduction and abstraction, is seen throughout the 1930s and 1940s, and exemplified by artists such as Gaston Lachaise, Sir Jacob Epstein, Henry Moore, Alberto Giacometti, Joan Miró, Ásmundur Sveinsson, Julio González, Pablo Serrano, Jacques Lipchitz and also by the 1940s abstract sculpture was impacted and expanded 	Modern sculpture

Since the 1950s Modernist trends in sculpture both abstract and figurative have dominated the public imagination and the popularity of Modernist sculpture had sidelined the traditional approach. Picasso was commissioned to make a maquette for a huge, -high public sculpture to be built in Chicago, known usually as the Chicago Picasso". He approached the project with a great deal of enthusiasm, designing a sculpture which was ambiguous and somewhat controversial. What the figure represents is not known; it could be a bird, a  horse, a woman, or a totally abstract shape. The sculpture, one of the most recognizable landmarks in downtown Chicago, was unveiled in 1967. Picasso refused to be paid $100,000 for it, donating it to the people of the city. In the late 1950s and the 1960s, abstract sculptors began experimenting with a wide array of new materials and different approaches to creating their work. Surrealist imagery, anthropomorphic abstraction, new materials and combinations of new energy sources and varied surfaces and objects became characteristic of much new modernist sculpture. Collaborative projects with landscape designers, architects, and landscape architects expanded the  outdoor site and contextual integration. Artists such as Isamu Noguchi, David Smith, Alexander Calder, Jean Tinguely, Richard Lippold, George Rickey, Louise Bourgeois, and Louise Nevelson came to characterize the look of modern sculpture. By the 1960s Abstract expressionism, Geometric abstraction and Minimalism, which reduces sculpture to its most essential and fundamental features, predominated. Some works of the period are: the Cubi works of David Smith, and the welded steel works of Sir Anthony Caro, as well as welded sculpture by a large variety of sculptors, the large scale work of John Chamberlain, and environmental installation scale works by Mark di  Suvero. Other Minimalists and Postminimalists include Tony Smith, Donald Judd, Robert Morris, Anne Truitt, Ronald Bladen, Giacomo Benevelli, Arnaldo Pomodoro, Richard Serra, Carl Andre, Dan Flavin, Eva Hesse, Christo, Walter De Maria, Robert Smithson, and others like John Safer who added motion and monumentality to the theme of purity of line, led contemporary abstract sculpture in new directions. During the 1960s and 1970s figurative sculpture by pop artists and modernist artists in stylized forms by artists such as: George Segal, Claes Oldenburg, Arman, Leonard Baskin, Ernest Trova, Marisol Escobar, Paul Thek, Manuel Neri and others became popular. In the 1980s  several artists, among others, exploring figurative sculpture were Robert Graham in a classic articulated style and Fernando Botero bringing his painting's "oversized figures" into monumental sculptures. Ceramic sculpture as practiced by Pablo Picasso, Peter Voulkos, Stephen De Staebler, Kenneth Price, and others became an important idiom of modern sculpture in the 20th century. Contemporary movements. Site specific and environmental art works are represented by artists: Andy Goldsworthy, Walter De Maria, Richard Long, Richard Serra, Robert Irwin, George Rickey, and Christo and Jeanne-Claude-led contemporary abstract sculpture in new directions. Artists created environmental sculpture on expansive sites in the  land art in the American West group of projects. These land art or "earth art" environmental scale sculpture works exemplified by artists such as Robert Smithson, Michael Heizer, James Turrell (Roden Crater). Eva Hesse, Sol LeWitt, Jackie Winsor, Keith Sonnier, and Bruce Nauman, among others were pioneers of Postminimalist sculpture. Also during the 1960s and 1970s artists as diverse as Eduardo Paolozzi, Chryssa, Walter De Maria, Claes Oldenburg, George Segal, Edward Kienholz, Nam June Paik, Wolf Vostell, Duane Hanson, and John DeAndrea explored abstraction, imagery, and figuration through video art, environment, light sculpture, and installation art in new ways. Conceptual  art is art in which the concept(s) or idea(s) involved in the work take precedence over traditional aesthetic and material concerns. Works include "One and Three Chairs", 1965, by Joseph Kosuth, and "An Oak Tree", 1973, by Michael Craig-Martin, and those of Joseph Beuys and James Turrell among others. Postmodern sculpture occupies a broader field of activities than Modernist sculpture. Rosalind Krauss identified sculpture in the expanded field, a series of oppositions around the work's relationship to its environment that describe the various sculpture-like activities that are postmodern sculpture, creating a theoretical explanation that could adequately fit  the developments of Land art, Minimalist sculpture, and site-specific art into the category of "sculpture": Minimalism. Contemporary genres. Modern sculpture is often created outdoors, as in environmental art and environmental sculpture, often in full view of spectators. Light sculpture and site-specific art also often make use of the environment. Site-specific artwork is intentionally created for a specific place. The term was first used in the mid-1970s by sculptors Patricia Johanson, Dennis Oppenheim, Athena Tacha, and others. Site specific environmental art was described as a movement by architectural critic Catherine Howett and art critic Lucy Lippard. Land art , Earthworks, (Earth art) is an art movement that makes specific use of the real landscape to form works of sculpture that are located in and make use of nature generally in altered form. It is a form of sculpture created in nature, from nature, using materials found in nature like dirt, soil, rocks, logs, branches, leaves, and water, as well as man made materials like Chain-link fencing, barbed wire, rope, rubber, glass, concrete, metal, asphalt, and mineral pigments. Ice sculpture is a form of ephemeral sculpture that uses ice as the raw material. It is popular in China, Japan , Canada, Sweden, and Russia. Ice sculptures feature decoratively in some cuisines, especially in Asia. Kinetic sculptures are sculptures that are designed to move, which include mobiles. Snow sculptures are usually carved out of a single block of snow about 6 to on each side and weighing about 20–30 tons. The snow is densely packed into a form after having been produced by artificial means or collected from the ground after a snowfall. Sound sculptures take the form of indoor sound installations, outdoor installations such as aeolian harps, automatons, or be more or less near conventional musical instruments. Sound sculpture is  often site-specific. Art toys have become another format for contemporary artists since the late 1990s, such as those produced by Takashi Murakami and Kid Robot, designed by Michael Lau, or hand-made by Michael Leavitt.
