Final answer:
The Ottawa Charter was developed at the First International Conference on Health Promotion by the World Health Organization (WHO), with the event hosted in Ottawa, Canada, in 1986. The charter represents a global effort to promote public health and was a collaboration between WHO and its member nations.
Step-by-step explanation:
The individuals involved in making the Ottawa Charter were those associated with the World Health Organization (WHO). WHO is a specialized agency under the umbrella of the United Nations (UN), which provides leadership on global health matters, shaping health research agendas, and monitoring and assessing health trends worldwide. The Ottawa Charter was a landmark event that aimed to promote public health by defining an approach to health promotion. It was developed at the First International Conference on Health Promotion held in Ottawa, Canada, in 1986, which was a collaboration between WHO and its member nations.
It is noteworthy that the Canadian Government played a host role, but the charter itself was an initiative of the World Health Organization. Other entities like the International Red Cross, the United Nations in its broader scope, or regional international governmental organizations (IGOs) were not directly involved in the creation of the Ottawa Charter.
