The Japanese-American artist Ruth Asawa (1926-2013) had every obstacle against her. But she succeeded, becoming one of the most important American sculptors of the second half of the 20th century, as can be seen in the retrospective dedicated to her by the Guggenheim Museum Bilbao until September 13, organized by MoMA San Francisco and MoMA New York, in collaboration with the Guggenheim New York. Asawa carved out her own niche with weightless sculptures made of woven wire, evocative of plant and marine forms. These are transparent, porous works. They are very often hung from the ceiling. And an extraordinary feature of her working method was that she integrated it into her family life.
