Johan Harmen Rudolf Köhler

Johan Harmen Rudolf Köhler (July 3, 1818 in Groningen – April 14, 1873 in Aceh) was a Dutch general who commanded the Dutch-Indonesian forces during the First Aceh Expedition (Aceh is on the northern tip of island Sumatra, today's Indonesia) started on April 8, 1873. The expedition failed to reach its goals and Köhler himself was shot in a skirmish. His tombstone can still be found in a cemetery in Jakarta now known as Taman Prasasti Museum.
