The Death and Life of Great American


Cities


Foreword to the Modem Library Edition



by Jane Jacobs



When I began work on this book in 1958, I expected merely to


describe the civilizing and enjoyable services that good city street life


casually provides-and to deplore planning fads and architectural


fashions that were expunging these necessities and charms instead of


helping to strengthen them. Some of Part One of this book: that's all I


intended.


But learning and thinking about city streets and the trickiness of city


parks launched me into an unexpected treasure hunt. I quickly found


that the valuables in plain sight -- streets and parks --were intimately


mingled with clues and keys to other peculiarities of cities. Thus one


discovery led to another, then another. Some of the findings from the


hunt fill the rest of this book. Others, as they turned up, have gone


into four further books. Obviously, this book exerted an influence on


me, and lured me into my subsequent life's work. But has it been


influential otherwise? My own appraisal is yes and no.


Some people prefer doing their workaday errands on foot, or feel they


would like to if they lived in a place where they could. Other people


prefer hopping into the car to do errands, or would like to if they had a


car. In the old days, before automobiles, some people liked ordering


up carriages or sedan chairs and many wished they could. But as we


know from novels, biographies, and legends, some people whose


social positions required them to ride --except for rural rambles --


wistfully peered out at passing street scenes and longed to participate


in their camaraderie, bustle, and promises of surprise and adventure.


In a kind of shorthand, we can speak of foot people and car people.


This book was instantly understood by foot people, both actual and


wishful. They recognized that what it said jibed with their own


enjoyment, concerns, and experiences, which is hardly surprising,


since much of the book's information came from observing and


listening to foot people. They were collaborators in the research.


Then, reciprocally, the book collaborated with foot people by giving


legitimacy to what they already knew for themselves. Experts of the


time did not respect what foot people knew and valued. They were


deemed old- fashioned and selfish --troublesome sand in the wheels of


progress. It is not easy for uncredentialed people to stand up to the


credentialed, even when the so-called expertise is grounded in


ignorance and folly. This book turned out to be helpful ammunition


against such experts. But it is less accurate to call this effect



Conversely, the book neither collaborated with car people nor had an


influence on them. It still does not, as far as I can see.


The case of students of city planning and architecture is similarly


mixed, but with special oddities. At the time of the books publication,


no matter whether the students were foot or car people by experience


and temperament, they were being rigorously trained as anticity and


antistreet designers and planners: trained as if they were fanatic car


people and so was everybody else. Their teachers had been trained


or indoctrinated that way too. So in effect, the whole establishment


concerned with the physical form of cities (including bankers,


developers, and politicians who had assimilated the planning and


architectural visions and theories) acted as gatekeepers protecting


forms and visions inimical to city life. However, among architectural


students especially, and to some extent among planning students,


there were foot people. To them, the book made sense. Their


teachers (though not all) tended to consider it trash or


house rambling


found its way onto required or optional reading lists --sometimes, I


suspect, to arm students with awareness of the benighted ideas they


would be up against as practitioners. Indeed, one university teacher


told me just that. But for foot people among students, the book was


subversive. Of course their subversion was by no means all my doing.


Other authors and researchers --notably William H. Whyte -- were


also exposing the unworkability and joylessness of anticity visions. In


London, editors and writers of The Architectural Review were already


up to the same thing in the mid-1950s.


Nowadays, many architects, and some among the younger generation


of planners, have excellent ideas --beautiful, ingenious ideas --for


strengthening city life. They also have the skills to carry out their


plans. These people are a far cry from the ruthless, heedless city


manipulators I have castigated. But here we come to something sad.


Although the numbers of arrogant old gatekeepers have dwindled with


time, the gates themselves are another matter. Anticity planning


remains amazingly sturdy in American cities. It is still embodied in


thousands of regulations, bylaws, and codes, also in bureaucratic


timidities owing to accepted practices, and in unexamined public


attitudes hardened by time. Thus, one may be sure that there have


been enormous and dedicated efforts in the face of these obstacles


wherever one sees stretches of old city buildings that have been


usefully recycled for new and different purposes; wherever sidewalks


have been widened and vehicular roadways narrowed precisely


where they should be -- on streets in which pedestrian traffic is


bustling and plentiful; wherever downtowns are not deserted after


their offices close; wherever new, fine-grained mixtures of street uses


have been fostered successfully; wherever new buildings have been


sensitively inserted among old ones to knit up holes and tatters in a


city neighborhood so that the mending is all but invisible. Some


foreign cities have become pretty good at these feats. But to try to
