Rudolph was christened March 13, 1814.
He opted for a military career in the Dutch army for the colony in the east.
May 3, 1837, he set sail for the Dutch East Indies from Hellevoet as a KNIL sergeant, on the vessel De vrouw Maria. He was registered in the Netherlands under the name of Rudolf Boeger.
Promoted to 2nd lieutenant as of March 8, 1838. Took part in the military actions of the 6th battalion infantry in 1840 in West-Sumatera. For this he was awarded the Military Willems Orde (Cross), 4th class.
Became 1st lieutenant on March 29, 1844, and captain on September 19, 1850. On home leave in the Netherlands he applied for a release of duties and was awarded a pension at the end of 1852.
(His indigenous companion and 3 children remained in the colony. A part of his pension was withheld to support these children.)
He then got married in 1854. On March 12 the church wedding was held in Burgsteinfurt (Germany) and March 31 the civil wedding in Enschede (the Netherlands).
A son was born May 23 that year and baptised in Burgsteinfurt. The family initially resided in Hengelo. Later they received permission to move to Lingen in Germany with retention of the Dutch pension. They kept a house on the "Marktplatz", where in the end they both passed away.
