Indonesian Christian prominent leaders such as Mr. Todung Sutan Gunung Mulia, Mr. Yap Thiam Hien, and Benjamin Thomas Philip Sigar, on behalf of the churches incorporated in DGI, established a Christian university of Indonesia (Yayasan Universitas Kristen Indonesia ) on July 18, 1953. Its membership was expanded with the support of Elviannus Katoppo, Ong Jan Hong, Aminudin Pohan, Seri Condar Nainggolan, Benjamin Prawirohadmodjo, Rev. Komarlin Tjakraatmadja, Gerrit Siwabessy, Tan Tek Heng, and J.C.T. Simorangkir. Three months later, on October 15, 1953, Universitas Kristen Indonesia was officially established with the faculties of Language and Philosophy, and Economics. During those first days, campus life and administration were held at HSK on Jalan Diponegoro 86 and at three apartments on Jalan Salemba 10.
