Braun, the most prominent donor for the congregation and church, travelled on behalf of Jerusalem's Association from Stuttgart to Jaffa to attend the inauguration of Immanuel Church, scheduled for Pentecost 1904 (May 22). Unfortunately he contracted dysentery after his arrival and died hospitalised in Jerusalem on 31 May 1904. He was buried on the Anglo-Prussian simultaneous Anglican-Evangelical Cemetery on Mount Zion, close to Samuel Gobat's grave.
