The auxiliary mission hospital at Sonder (Minahassa) was opened in 1907. It was initiated by the Association “Karapatan Sonder”. The Dutch Missionary Organization NZG
financed two deaconesses. (From: ” Tien jaar in de Minahassa, 1909-1919″ ,by Joh. H. Duyverman, edited by Dr. Chr.G.F. de Jong, p.XII). See also : ” Een paar mededelingen van Br. Schoch at Sonder” (A few announcements on the hospital at Sonder) : The supply of medical care was very limited between 1901 and 1919.
In the Minahassa there were only three doctors, among whom a European doctor at the Menado hospital. There was also a hospital at Tondano and the mentioned auxiliary hospital at Sonder with two Dutch nurses. And there was an outpatient clinic at Kawangkoan. The use of these facilities was limited as the population was afraid of being treated by these institutions.
