ABSTRACT

Tyrwhitt probably found the hectic pace of work a welcome distraction from worrying about her brother Cuthbert and sister-in-law Delia in Singapore, which, in January 1942, was threatened by an imminent Japanese Army invasion. Tyrwhitt was eager to get on with the new work at APRR: producing a new series of maps, mostly on aspects of "social health". A good example of Tyrwhitt's inventive map making is the set of maps she devised for the National Federation of Women's Institutes. The contacts Tyrwhitt established with National Council for Social Service (NCSS) stimulated her thinking about regional planning based on the cell principle at a new scale: the "neighborhood unit", a residential area centered on civic facilities. Under Tyrwhitt's supervision, the APRR team approached the survey from a regional planning perspective that integrated the new industrial site as a part of a comprehensive plan for the growth of an adjacent town, accommodating housing, open space, and agriculture.
