Passage: Differences between Moynier and Dunant developed early over the reach of the organization's authority and its legal and organizational formation. The key point of dispute was Dunant's idea to grant neutrality to wounded soldiers and medical staff in order to protect them. Moynier was a determined opponent of this plan, which he did not consider realistic and thought its insistence risked the collapse of the project. Dunant, however, was able to persuade powerful political and military figures in Europe of his ideas, and with the first Geneva Convention in 1864 had some success toward their implementation. In that same year however, Moynier took over the position of President of the International Committee.

Question: Which role on the International Committee did Moynier step in to take?
