The most ambitious painting by America's premier Impressionist artist, Mary Cassatt (1844-1926), was Modern Woman (fig. 1), a mural created for the Woman's Building at the 1893 World's Columbian Exposition in Chicago. Cassatt's mural and its companion Primitive Woman (fig. 2) by her colleague Mary Fairchild MacMonnies (1858-1946) celebrated, along with the building itself, women's progress and achievements. These two murals were among the most important public commissions of the early 1890s in the United States. Unfortunately, like other World's Columbian Exposition projects that survived the demolition of the fairgrounds after the close of the fair on 31 October 1893, these murals are currently unlocated.'Renewed interest in" The White City," as the fair was popularly known, and the present-day reassessment of art made by women have, however, yielded fresh evidence of the murals' disposition and whereabouts during the first decades of the twentieth century.
