 At the end of the Eighth International Congress of Philosophy, held in Prague in September of 1934, Neurath proposed a series of International Congresses for the Unity of Science. These took place in Paris, 1935; Copenhagen, 1936; Paris, 1937; Cambridge, England, 1938; Cambridge, Massachusetts, 1939 and Chicago, 1941. For the organization of the congresses and related activities, Neurath founded the Unity of Science Institute in 1936, which was renamed in 1937 as the International Institute for the Unity of Science, alongside the International Foundation for Visual Education, founded in 1933. The Institute’s executive committee was composed of Neurath, Philip Frank and Charles Morris.
