Between 1924 and his death in 1959, Frank Lloyd Wright made designs for some twenty high-rise buildings of which only two were built. The towers form only a small part of his oeuvre; this book proposes a unique look at Wright as urbanist, an aspect of the master that has not been previously explored. Ballon's sustained study shows how his towers crystallize significant ideas about his architecture and American urbanism in the age of automobiles and suburbanization.
