Wright reacted grumpily when his grandiose vision was not immediately embraced by the Madison establishment. Wright's chaotic and controversial personal life (multiple marriages, bad debts, and an eventual FBI investigation into his alleged lack of patriotism) may have contributed to the ambivalence of Madison officialdom, but there was also the expense -- an estimated $17 million in 1938. When challenged, Wright spoke with typical disdain. "Madison could dig into its pocket and pay something for the charm nature has given it," the architect said. "But maybe Madison can't look ahead 10 years. It is too provincial, backwater, smug and satisfied." It took nearly six decades for Madison to act, and of course Wright wasn't alive to see his vision realized. The last years of his life, however, were among his most productive. Thirty percent of his buildings were created during the last decade of his life, including the Guggenheim Museum in New York and Madison's Unitarian Meeting House. More than one-third of Wright's buildings are listed on the National Register or are in a National Historic District. Fourteen of his buildings are National Historic Landmarks.
