Robert Charles Wallace
It was during his tenure at Queen’s that Wallace became highly regarded nationally (and internationally) as an extremely effective and efficient academic administrator. He was one of just three Canadians chosen to represent the country at the United Nations Conference for the establishment of an educational and cultural organization (ECO/CONF) held in London in November 1945. It was at this conference that the United Nations Educational, Scientific, and Educational Organization (UNESCO) was created. Additionally, Wallace received honorary degrees from twenty different universities.
Philip H. Coombs
Coombs was appointed by President John F. Kennedy to be the first Assistant Secretary of State for Education and Culture in February, 1961. He was an advocate for overhauling the educational system, saying that every school district should put 2% of its money into educational research and hire a "Vice President in charge of heresy."  During his stint in this post, he went to live in Paris, organizing the UNESCO International Institute for Educational Planning. This UNESCO-created group advised countries on improvements to their systems of education. Being dissatisfied with the pace of change, he resigned from the U.S. State Department in 1962 and, from 1963 to 1968, held the post of Director of the IIEP. He served as vice-chair and chair of the International Council of Economic Development until 1992, when he retired.
