The WHO was first proposed as part of the new United Nations programme to reform the post-war world. The idea for an international health organisation to help promote good health globally was put forward by a member of the Chinese delegation, Szeming Sze. His memoirs reveal the political difficulties which dogged the process and his son remembers his passion for the project. We also hear from historian, Professor Theodore M Brown on what was really going on behind the scenes.
