International non governmental organization that assists in worldwide physics development

The International Union of Pure and Applied Physics (IUPAP; '/aɪ//juː//p//æ//p//, /'/juː// /) is an international non governmental organization whose mission is to assist in the worldwide development of physics, to foster international cooperation in physics, and to help in the application of physics toward solving problems of concern to humanity. It was established in 1922 and the first General Assembly was held in 1923 in Paris. The Union is domiciled in Geneva, Switzerland. IUPAP carries out this mission by: sponsoring international meetings; fostering communications and publications; encouraging research and education; fostering the free circulation of scientists; promoting international agreements on the use of symbols, units, nomenclature and standards; and cooperating with other organizations on disciplinary and interdisciplinary problems. IUPAP is a member of the International Science Council. IUPAP is the lead organization promoting the adoption of the International Year of Basic Sciences for Sustainable Development, a proposal to be considered by the 76th session of the UN General Assembly.

In 1919 was formed the International Research Council “largely through the representatives of the National Academy of Sciences, Washington, and of the Royal Society, London, to coordinate international efforts in the different branches of sciences, under whose aegis international associations or unions in different branches of science could be formed". In accordance with this principle, the 1922 General Assembly of the IRC convened at Brussels and a number of physicists present decided that the formation of a Physics Union was imperative. Thirteen countries (Belgium, Canada, Denmark, France, Netherlands, Empire of Japan, Norway, Poland, Spain, Switzerland, United Kingdom, United States and Union of South Africa) immediately announced their adherence to the new Union. An Executive committee was formed which undertook to prepare rules, regulations, and activities of the organization. The committee consisted of ten distinguished physicists: W. H. Bragg, M. Brillouin, O. M. Corbino, M. Knudsen, M. Leblanc, R. A. Millikan, H. Nagaoka, E. Van Aubel, and H. Abraham. The committee had Bragg as President, Van Aubel as Vice President, and Abraham as Secretary. This was the birth of the International Union of Pure and Applied Physics.

The IUPAP President is the head of the Executive Council. IUPAP Presidents are elected by the General Assembly. During the election of the Executive Council, the future President is also elected to the post of President Designate. Thus in every Executive Council the current President Designate will succeed the incumbent President. Below is the list of IUPAP Presidents since its inception in 1922.

IUPAP, whose mission is to assist in the worldwide development of physics, to foster international cooperation, and to help in the application of physics toward solving problems of concern to humanity, has throughout its history defended the stand that no scientists should be barred from participating in conferences or events on the basis of their nationality or their affiliation. To alleviate sanctions in science and to promote principles and policies for international scientific collaboration, IUPAP offers physicists, including students, from any country around the world, who feel excluded from academic exchange based exclusively on their affiliation and/or country of origin, to apply to use the IUPAP as their affiliation.
