Simone in a Blue Bonnet 1903 Mary Cassatt 2

Mary Stevenson Cassatt ( /kəˈsæt/; May 22, 1844 – June 14, 1926) was an American painter and printmaker. She lived much of her adult life in France, where she first befriended Edgar Degas and later exhibited among the Impressionists. Cassatt often created images of the social and private lives of women, with particular emphasis on the intimate bonds between mothers and children.

She was described by Gustave Geffroy in 1894 as one of "les trois grandes dames" of Impressionism alongside Marie Bracquemond and Berthe Morisot.

Impressionism was a 19th-century art movement that originated with a group of Paris-based artists whose independent exhibitions brought them to prominence during the 1870s and 1880s in spite of harsh opposition from the art community in France. The name of the style is derived from the title of a Claude Monet work, Impression, soleil levant (Impression, Sunrise), which provoked the critic Louis Leroy to coin the term in a satiric review published in the Parisian newspaper Le Charivari.

Characteristics of Impressionist paintings include relatively small, thin, yet visible brush strokes; open composition; emphasis on accurate depiction of light in its changing qualities (often accentuating the effects of the passage of time); common, ordinary subject matter; the inclusion of movement as a crucial element of human perception and experience; and unusual visual angles. The development of Impressionism in the visual arts was soon followed by analogous styles in other media which became known as Impressionist music and Impressionist literature.
