Slate has a very good historical slideshow about Frank Lloyd Wright and the growth and development of the Guggenheim Museum. The focus is unusual as it is as much on the development of the collection as it is about the building itself.
It is astonishing that a museum that is 50 years old still generates controversy, but in many ways the Guggenheim is ur-project that posed the question we still wrestle with: Which comes first, the art or the architecture? It is not surprising where Wright comes down:
architecture is "the Mother-art of which Painting is but a mere daughter"Artists, and some curators, might differ, as they did, vociferously, when the Guggenheim first opened.
