The Greater London Plan of 1944 was developed by Sir Leslie Patrick Abercrombie (1879-1957). The plan was directly related to the County of London Plan written by Abercrombie in 1943, with contributions by John Henry Forshaw (1895-1973). Following World War II, London was presented with an opportunity to amend the perceived failings of unplanned and haphazard development that had occurred as a result of rapid industrialisation in the nineteenth century.
