Frank Lloyd Wright's masterpiece opened to the public on October 21, 1959, six months after his own death, and was immediately recognized as an architectural landmark. The Solomon R. Guggenheim Museum is arguably the most important building of Wright's late career. A monument to modernism, the unique architecture of the space, with its spiral ramp riding to a domed skylight, continues to thrill visitors and provide a unique forum for the presentation of contemporary art. In the words of Paul Goldberger, "Wright's building made it socially and culturally acceptable for an architect to design a highly expressive, intensely personal museum. In this sense almost every museum of our time is a child of the Guggenheim.
