Baron von Wurmb was also an important member of the Batavia Society of Arts and Sciences (now National Museum) and the founder of its well-known library, now the National Library. He lived in a house in the old Batavia area, known as the Yellow Lions building, due to the two golden (now faded) lion statues that guard the entrance of the house. Though now slightly run down, the building still stands next to Kali Besar in Jakarta.
