James McNeill Whistler in the context of "Art for art's sake"

An art critic is a person who is specialized in analyzing, interpreting, and evaluating art. Their written critiques or reviews contribute to art criticism and they are published in newspapers, magazines, books, exhibition brochures, and catalogues and on websites. Some of today's art critics use art blogs and other online platforms in order to connect with a wider audience and expand debate.

Marc Gabriel Charles Gleyre (2 May 1806 – 5 May 1874), was a Swiss artist who was a resident in France from an early age. He took over the studio of Paul Delaroche in 1843 and taught a number of younger artists who became prominent, including Henry-Lionel Brioux, Jean-Léon Gérôme, George du Maurier, Claude Monet, Pierre-Auguste Renoir, Louis-Frédéric Schützenberger, Alfred Sisley, Auguste Toulmouche, and James McNeill Whistler.

Aubrey Vincent Beardsley (/ˈbɪərdzli/ BEERDZ-lee; 21 August 1872 – 16 March 1898) was an English illustrator and author. His black ink drawings were influenced by Japanese woodcuts, and depicted the grotesque, the decadent, and the erotic. He was a leading figure in the aesthetic movement which also included Oscar Wilde and James McNeill Whistler. Beardsley's contribution to the development of the Art Nouveau and poster styles was significant despite his early death from tuberculosis. He is one of the important Modern Style figures.

Arrangement in Grey and Black No. 1, best known under its colloquial name Whistler's Mother or Portrait of Artist's Mother, is a painting in oils on canvas created by the American-born painter James McNeill Whistler in 1871. The subject of the painting is Whistler's mother, Anna McNeill Whistler. The painting is 56.81 by 63.94 inches (1,443 mm × 1,624 mm), displayed in a frame of Whistler's own design. It is held by the Musée d'Orsay in Paris, having been bought by the French state in 1891. It is one of the most famous works by an American artist outside the United States. It has been variously described as an American icon and a Victorian Mona Lisa.

Joseph William Comyns Carr (1 March 1849 – 12 December 1916), often referred to as J. Comyns Carr, was an English drama and art critic, gallery director, author, poet, playwright and theatre manager.

Beginning his career as an art critic, Carr was a vigorous advocate for Pre-Raphaelite art and a vocal critic of the "short-sighted" art establishment. In 1877 he became a director of the Grosvenor Gallery and promoting Pre-Raphaelite painters and other important exhibitors, such as James McNeill Whistler, Dante Gabriel Rossetti and Edward Burne-Jones. Ten years later he founded the rival New Gallery.

Harmony in Blue and Gold: The Peacock Room (better known as The Peacock Room) is a work of interior decorative art created by James McNeill Whistler and Thomas Jeckyll, translocated to the Freer Gallery of Art in Washington, D.C., which is part of the Smithsonian's National Museum of Asian Art. Whistler painted the paneled room in a unified palette of blue-greens with over-glazing and metallic gold leaf. Painted between 1876 and 1877, it now is considered one of the greatest surviving Aesthetic interiors, and best examples of the Anglo-Japanese style.

American realism was a movement in art, music and literature that depicted contemporary social realities and the lives and everyday activities of ordinary people. The movement began in literature in the mid-19th century, and became an important tendency in visual art in the early 20th century. Whether a cultural portrayal or a scenic view of downtown New York City, American realist works attempted to define what was real.

In the U.S. at the beginning of the 20th century a new generation of painters, writers and journalists were coming of age. Many of the painters felt the influence of older U.S. artists such as Thomas Eakins, Mary Cassatt, John Singer Sargent, James McNeill Whistler, Winslow Homer, Childe Hassam, J. Alden Weir, Thomas Pollock Anshutz, and William Merritt Chase. However they were interested in creating new and more urbane works that reflected city life and a population that was more urban than rural in the U.S. as it entered the new century.
