He inaugurated the Batavian Society of Arts and Sciences (now the National Museum of Indonesia) in 1778, while also finding the time to catalogue flora and fauna of Java and Sumatra. In 1781 he became Commissioner Concerning the Fleet and the Army, and Common Council of India but two years later decided to return home for health reasons. However, on Christmas Eve 1783 in the Indian Ocean, as he sailed back to Holland, he was murdered during a mutiny on board ship. [See Radermachera.]

Many of his works were translated into several languages and some became standard texts for students from both the Islamic and European disciplines. He was physician to the royal court, and head not only of a hospital in Baghdad but also one in the City of Rayy (the city where he was born and eventually died). [See Rhazya.]
