This exhibition from the National Portrait Gallery examines attitudes towards sexuality and difference in American art from the late 19th century to the present. Some of the artists in the show are homosexual; some are heterosexual; and the sexuality of the subjects of the works varies as well. As one of the curators, Jonathan Katz, says, "it's impossible ... to weed gay from straight in the course of the development of American Art. It's utterly integrated." The online exhibition show is divided into galleries, such as "Before Difference", which begins with a portrait of Walt Whitman. The gallery "Stonewall and After", commences with a young and happy Robert Mapplethorpe self-portrait, taken in 1975, while an older and more somber Mapplethorpe appears in the AIDS gallery, photographed in 1988. The multimedia section is also worth a visit, as visitors can hear short commentaries on selected works by curators Jonathan Katz and David Ward. There is also a 42-minute recording of Katz, James Boaden, and Dominic Johnson at the scholarly symposium "Addressing (and Redressing) the Silence: New Scholarship in Sexuality and American Art," January 29, 2010.
