Architect Jeanne Gang on changing the shape of a city

Jeanne Gang, arguably the most important female architect working today, heads her own firm, Studio Gang, which is pushing the boundaries of the good that architecture can do, for connecting communities and for the environment. Gang talked with correspondent Martha Teichner about her most recent project, an expansion of New York’s American Museum of Natural History, and about the skyscrapers, airport terminal, and other civic spaces she has designed in her hometown of Chicago meant to transform spaces, outside and within.
