"In Urban Utopias in the Twentieth Century ... three plans are presented in depth. Working from hitherto unpublished layouts, sketches, manuscripts, and letters, the author has reconstructed the fascinating historical context out of which the plans emerged ... Fishman shows the utopian origins of all three plans, the social innovations that the architects hoped to achieve, and their heroic but vain attempts to impose a 'perfect' design on an imperfect world"--Dustjacket.
