P. C. Chang
On the Universal Declaration of Human Rights drafting committee, he served both as an effective Asian delegate and also as a mediator when the negotiations reached a stalemate. He served as Vice-Chairman of the original UN Commission on Human Rights and Republic of China delegate to committee and played a pivotal role in its drafting of the Universal Declaration of Human Rights (UDHR) of 1948. He and fellow delegate Charles Malik, the Lebanese philosopher-diplomat, shared ideals of universal human rights, but debated what they were and how they could be described in an international document. By most accounts, Chang and Malik were the philosophical leaders of the deliberations. Chang argued that the modern world should pay heed to Chinese philosophers such as Mencius not because they were Chinese, but because their ideas had universal validity.
John Peters Humphrey
Humphrey was a principal drafter of the Universal Declaration of Human Rights. After consulting with the executive group of the Commission, chaired by Eleanor Roosevelt, Professor Humphrey prepared the first preliminary draft of what was to become the Universal Declaration of Human Rights. On the night of December 10, 1948, the General Assembly unanimously adopted the Declaration, dubbed by Mrs. Eleanor Roosevelt as "the international Magna Carta of all humankind."
