Geddes Plan?

I assume this is a reference to the 1925 master plan for Tel-Aviv, drawn up by biologist and town planner Patrick Geddes (not Gaddis!).

in reference to:

"Goldman's proposal would institutionalize a phenomenon that was defined in the 1920s by the Gaddis plan and tends to happen spontaneously."
