Peigi Rockwell is the Project Lead for Ribbons of History and co-chairs the Task Force for 99th Street. Also known as Margaret Rockwell, she is a Canadian urban historian and occasionally lectures on Canadian History at the University of Alberta. While working on Ribbons of History she completed and defended her PhD dissertation on modernist planning practices during the urban renewal years in Buffalo, New York and Hamilton, Ontario (1949-1974). Her research helped her to understand the importance of pedestrians to healthy urban streets. She also learned how important it is for a city to avoid thoroughfares of free-flowing traffic cutting and separating the urban environment into isolated zones. A healthy urban street is a street with lots of successful shops, enthusiastic pedestrians and conscientious drivers – this is her goal for 99th Street.
