Jane Jacobs, the writer and thinker who brought penetrating eyes and ingenious insight to the sidewalk ballet of her own Greenwich Village street and came up with a book that challenged and changed the way people view cities, died today in Toronto, where she lived. She was 89.

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.
