Ruth Asawa: Retrospective by Janet Bishop A landmark survey of the wide-ranging practice of one of the twentieth century’s most innovative artists   Best known for her sinuous looped-wire sculptures, Ruth Asawa (1926–2013) used everyday materials to create endlessly innovative works in a variety of media over her more than six-decade-long career, from her student days at the experimental Black Mountain College in the 1940s through her mature years in her adopted home city of San Francisco.
