[1] In January 1929 Foundoukidis became an attache at the Section of Artistic Relations in the International Institute of Intellectual Cooperation (IIIC), an advisory body to the League of Nations.
[1] With Foundoukidis as its effective leader the IMO began to organize international conferences which drew very large numbers of attendees.
[4] The Germans were generally opposed to the IIIC and would not cooperate with the IMO or other League of Nations units, but to some extent Foundoukidis was able to counteract this divide through his diplomacy and human qualities, creating strong personal but unofficial links.
When stelae removed from Tell el-Amarna in Egypt were illegally exported and offered for sale in Europe, Foundoukidis advised that the OIM draft applied to both movables and immovables, such as "fragments of monuments".
[6] During the Spanish Civil War, on 16 November 1936 eight incendiary bombs fell on the Museo del Prado in Madrid, causing considerable damage to the structure.
The plan and photographs were published in Mouseion, the press organ of the International Office of Museums, directed by Foundoukidis, in October 1937.
