Malcolm Adiseshiah
From 1 to 16 November 1945 a United Nations Conference was convened in London for the establishment of an educational and cultural organization (ECO/CONF). In the conference, a new organization was created to establish the “intellectual and moral solidarity of mankind” and thus prevent the outbreak of another world war. The United Nations Educational, Scientific and Cultural Organization (UNESCO) was founded by thirty-seven countries. Its Constitution to promote collaboration between member states in the fields of education, science and culture was signed on 16 November 1945 and came into force on 4 November 1946. Sarvepalli Radhakrishnan, former President of India, was a former student of Adiseshiah’s father. He made a referral to Sir Julian Huxley, then Director-General of UNESCO, who invited Adiseshiah to the organization in 1948. He was posted as Deputy Director of the department of exchange of persons. In that capacity Adiseshiah signed the UNESCO Fellowship letter in 1949 to M. S. Swaminathan, eminent scientist and administrator, to pursue research at the Agricultural University in Wageningen, the Netherlands which was the starting point of his illustrious career.
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.
