In a rather early stage we meet the ‘inrigting voor de verpleging van behoeftige zieke inlanders’ (indigenous hospital) Probolinggo (Pasoeroean). In the Koloniaal Verslag 1878 (Colonial Report) this hospital was accepted by the NI Government to meet the healthcare  needs of the poor patients of Probolinggo. For this purpose the hospital could engage a mandoor and a female servant, paid for by the Government. The supervision was assigned to a member of the staff of the local prison (NI Statutebook 1878 no. 77).
Many years later the Addendum to the NI Statutebook of 1927 (Bijblad no. 11446 of 27 August 1927) mentions the GBZ at Probolinggo which is allowed to charge patients in nursing class 4 (nursing tariff 1.50 a day). This meant that it was a rather simple hospital.

In the 1930s, Probolinggo was a Residency, regency and district with a principal town of the same name, situated in the province of East Java. The Residency comprises the regencies Probolinggo, Kraksaan and Loemadjang and has 947,000 inhabitants, of whom 3,000 Europeans and 9,000 Chinese. At the borders with the Residency Malang the Tengger mountains are foundd with the Gunung Bromo (2292m) and the gunung Semeroe (3676 m). The main city of Probolinggo is situated on Strait Madoera and on the railway to the south. The town has a municipal council and a mayor and has 37,000 inhabitants, of whom 900 Europeans and 3,600 Chinese (Gonggryp 1934, 1206).

See the Grote Atlas van Nederlands-Indie (Asia Maior, KNAG 2003), p. 339 for a map of the city. The hospital is marked by the figure 12.
