Max Kohnstamm (*1914) is a pioneer of post-war European unification. As Jean Monnets right-hand man he was closely involved in the establishment and design of the European Union (EU) as we know it today. Up to the present day he devotes himself to a solid European and international community of law, aimed at effectively banning unilateral power aspirations and interstate violence. As a surviver of Hitlers Nacht und Nebel the young Dutch diplomat and former secretary to Queen Wilhelmina found himself both impressed and greatly inspired by Monnets campaign for supranationally organising the states of Europe as an alternative for war. Kohnstamm acted as secretary-general of the first European government, the High Authority of the European Coal and Steel Community. In 1956 he left office to assist Monnet and the latters Action Committee for the United States of Europe. The two men constituted a team that exerted far-reaching influence behind the scenes of European and global diplomacy. In 1974 Kohnstamm became the first president of the European University Institute in Florence. In later years he played a remarkable role in Jacques Delors policy drive for completing the EUs Common Market. Anjo G.
