The Life and Death of Jane Jacobs

The woman who saved New York City's West Village from Robert Moses's bulldozer has passed away. Jane Jacobs rejected modern architecture's monstrous high rises, with its empty plazas and separation of people from their livelihood.

In her book "Death and Life of Great American Cities," written in 1961, Ms. Jacobs's enormous achievement was to transcend her own withering critique of 20th-century urban planning and propose radically new principles for rebuilding cities. At a time when both common and inspired wisdom called for bulldozing slums and opening up city space, Ms. Jacobs's prescription was ever more diversity, density and dynamism — in effect, to crowd people and activities together in a jumping, joyous urban jumble.

Ms. Jacobs's thesis was supported and enlarged by her deep, eclectic reading. But most compelling was her description of the everyday life she witnessed from her home above a candy store at 555 Hudson Street.

She puts out her garbage, children go to school, the drycleaner and barber open their shops, housewives come out to chat, longshoremen visit the local bar, teenagers return from school and change to go out on dates, and another day is played out. Sometimes odd things happen: a bagpiper shows up on a February night, and delighted listeners gather around. Whether neighbors or strangers, people are safer because they are almost never alone.
