Johannes Rach was a Danish painter and draughtsman whose works from Copenhagen and Indonesia are a valuable source of architectural and cultural historic knowledge. He began his artistic career painting topographical views for the royal court in Copenhagen, mosrlt in close collaboration with Hans Heinrich Eegberg without any clear indication of who painted whatm and credits are therefore often given to Rach & Eegberg. Later he traveled to the Dutch East Indies, by way of Saint Petersburg and the Netherlands, where he settled in Batavia, and had a military career in the Royal Dutch East Indies Army. At the same time he continued to pursue his artistic work with considerable commercial success. He set up a large studio with local employees who worked in his style, and produced depictions of the city and surrounding countryside for the local elite.
