Sir Leslie Patrick Abercrombie was an English architect and town
planner who became Professor of Civic Design at the Liverpool
University and then Professor of Town Planning at University College
London. He was also involved with the Council for the Preservation of
Rural England (CPRE). Abercrombie is best known for the work he did with
J H Forshaw on the Country of London Plan (1943) and the Greater London
Plan (1944). They contain perhaps the greatest landscape and open space
strategy ever formulated for a capital city, and certainly the best
that London has had. The idea was to create a web of open space leading
from the city centre, through green corridors, greenways and green
wedges to a green belt on the periphery of London. Beyond the Green
Belt, Abercrombie proposed the layout of New Towns.
