Lauren Elkin, whose book Flâneuse: Women Walk the City is profiled on the Resources page, contributed a radio essay to the BBC on the types of pedestrians one encounters on urban sidewalks: “Elkin reckons that the way people walk, their gait, is a signifier. It also tells us something about ourselves as we watch people file past us, the quick and the slow. And it makes her think of George Sand strolling Paris.”
