”An urbanist and activist whose writings championed a fresh, community-based approach to city building. She had no formal training as a planner, and yet her 1961 treatise, The Death and Life of Great American Cities, introduced ground-breaking ideas about how cities function, evolve and fail, that now seem like common sense to generations of architects, planners, politicians and activists. Jacobs saw cities as integrated systems that had their own logic and dynamism which would change over time according to how they were used. With an eye for detail, she wrote eloquently about sidewalks, parks, retail design and self-organization. She promoted higher density in cities, short blocks, local economies and mixed uses. Jacobs helped derail the car-centred approach to urban planning in both New York and Toronto, invigorating neighborhood activism by helping stop the expansion of expressways and roads.”
