works by John Flannagan (1895–1942), Robert Laurent (1890–1970), and Elie Nadelman (1882–1946). Signature works by Alexander Calder (1898–1976) and Louise Nevelson (1899–1988) are among the mid-twentieth century sculptural pieces in the collection. Nevelson’s Lunar Landscape is a large, painted-wood construction that dates to 1959-60 (see picture gallery below). American Impressionist paintings and 20th-century modernist works The ACMAA collection contains several examples of American Impressionism. Idle Hours (about 1894) by William Merritt Chase (1849–1916) anchors the ACMAA holdings of American Impressionist paintings. Chase's student and protégé Julian Onderdonk (1882–1922) is represented by a Texas scene, A Cloudy Day, Bluebonnets near San Antonio, Texas (1918). Flags on the Waldorf (1916) is a signature New York work by Childe Hassam (1859–1935). Other well-known American Impressionist painters who have pieces in the collection are Mary Cassatt (1844–1926), Willard Metcalf (1858–1925), and Dennis Miller Bunker (1861–1890; see picture gallery below). New York photographer Alfred Stieglitz (1864–1946) befriended and championed several of the most visionary modern painters to emerge in early twentieth-century America. Five modern artists who were closely identified with Stieglitz's circle are represented in the ACMAA collection. They are Charles Demuth (1883–1935), Arthur G. Dove (1880–1946), Marsden Hartley (1877–1943), John Marin (1870–1953), and Georgia O'Keeffe (1887–1986). The collection houses early works by Demuth, Dove, Hartley, and O’Keeffe, produced between 1908 and 1918, and a focused group of later paintings by Dove, Hartley, Marin, and O’Keeffe that capture their response to the light and color of the New Mexican landscape near Taos. Charles Demuth’s Chimney and Water Tower (1931), painted in the artist’s hometown of Lancaster, Pennsylvania, depicts a local linoleum factory as a grid of austere, monumental forms and passages of steel gray, blue, and deep red. Chimney and Water Tower entered the ACMAA collection in 1995. Several important paintings by American modernist Stuart Davis (1892–1964) are housed in the Amon Carter Museum of American Art, including an early self-portrait painted in 1912 and a work from his Egg Beater series, Egg Beater No. 2 (1928). American modernists represented in the AMCAA collection also include Josef Albers (1888–1976), Will Barnet (1911–2012), Oscar Bluemner (1867–1938), Morton Schamberg (1881–1918), Ben Shahn (1898–1969), Charles Sheeler (1883–1965), Joseph Stella (1877–1946), and others (see picture gallery below).
