Ann Hamilton presented a lecture on her nearly 30-year career as part of the Diamonstein-Spielvogel Lecture Series at the National Gallery of Art on September 16, 2011. Hamilton has made multimedia installations with stunning qualities and quantities of materials: a room lined with small canvas dummies, a table spread with human and animal teeth, the artist herself wearing a man's suit covered in a layer of thousands of toothpicks. Along the way, she has constantly set and reset the course of contemporary art. Often using sound, found objects, and the spoken and written word, as well as photography and video, her objects and environments invite us to embark on sensory and metaphorical explorations of time, language, and memory. Textiles and fabric have consistently played an important role in her performances and installations—whether she is considering clothing as a membrane or (more recently) treating architecture itself as a kind of skin. The Gallery owns 15 works by the artist, including photographs, prints, sculptures, and a video installation.
