The International Association of Applied Psychology (IAAP) was officially founded in 1920 in Geneva as the first international academic society within the field of psychology. It was initially called Association Internationale de Psychotechnique in French.
Some years later, during its congress, which took place in Paris, in 1953, Applied Psychology was added to the Association’s original name. And the name officially became in English the International Association of Applied Psychology in London in 1955.
Among the 16 first Presidents of IAAP, let us note that nine of them are European, five came from the USA and Canada, and one came from Australia. Only two were women, both from France - Claude Lévy-Leboyer became President in 1982, after 62 years of male leadership. Christine Roland-Lévy became President of IAAP, as the second woman President, some 28 years later.
