Knowra Jane Jacobs Jane Jacobs Jane Jacobs was an American-Canadian writer and activist whose books challenged modernist urban planning and argued that dense, mixed-use neighborhoods thrive through the knowledge and daily activity of their residents.
Robert Moses : Robert Moses was a New York public official who built highways, parks, and public works while wielding extensive planning authority. His highway and redevelopment projects made him Jacobs’s most consequential opponent in New York.
Mixed-use development : Mixed-use development combines residential, commercial, or other functions within the same area or building. Jacobs argued that mixing uses brings people into streets at different times.
Urban renewal : Urban renewal is government-led redevelopment that clears or substantially reshapes existing urban areas. Jacobs opposed clearance projects that displaced residents and destroyed functioning neighborhoods.
The Death and Life of Great American Cities : The Death and Life of Great American Cities is Jane Jacobs’s 1961 critique of modernist urban planning. This book set out her best-known account of how diverse neighborhoods sustain urban life.
William H. Whyte : William H. Whyte was an American urbanist and journalist known for studying how people use public spaces. His street-level observations complemented Jacobs’s attention to everyday urban life.
Urban density : Urban density measures how many people or buildings occupy a given area. She distinguished useful neighborhood density from overcrowding and uniform high-rise development.
Lower Manhattan Expressway : The Lower Manhattan Expressway was a proposed highway that would have crossed parts of lower Manhattan. Jacobs helped mobilize opposition that contributed to its cancellation.
New Urbanism : New Urbanism is an urban design movement promoting walkable, compact, mixed-use communities. Its goals overlap with neighborhood qualities Jacobs championed, though the movement developed later.
Lewis Mumford : Lewis Mumford was an American historian and critic of technology, architecture, and urban development. His critique of Jacobs exposed disagreements over density, neighborhood life, and planning.
Street vitality : Street vitality is the sustained presence of people and activity in public streets. Jacobs treated frequent everyday use as a source of safety and neighborhood life.
