As a scientist, Professor Emeritus, and former member of the university's Board of Trustees, AP might have been in favour of the plan for a new physics building on the Queen's University campus. But the Board had chosen a site that would destroy the last large green space on campus. Students and faculty protested, demonstrations were held, and the Board was forced to change its decision.
An alternative site was chosen on Queen's Crescent, where most of the property owners had agreed to sell. Just one person held out. It was Archie and Cordelia's daughter, Phyllis Knight, who had lived at 52 Queen's Crescent for nearly 70 years.
