the appointment of former Prime Minister Lester B. Pearson as a lecturer. The newly opened school was a natural fit for Pearson, who had won the Nobel Peace Prize in 1957 for trying (without significant impact) to end the Suez conflict. Senator Paterson later contended that the creation of the school and thoughts about how Pearson would spend his retirement were "intimately bound together in [the Senator’s] mind."

This was controversial given the government of South Africa's Apartheid policy. The NPSIA Faculty Council was concerned that Uren had represented himself as speaking on behalf of Carleton University, and passed a resolution censuring Uren for damaging NPSIA's reputation. The incident was complicated by the fact that Uren also served as the director of the Paterson Centre, Carleton's administrative centre for international exchanges. His dual role as professor and
