Sim Keng Koen

Sim Keng Koen, Kapitein der Chinezen (died in 1906) was a Chinese-Indonesian bureaucrat and the patriarch of the influential Lauw-Sim-Zecha family, part of the 'Cabang Atas' gentry of the Dutch East Indies (now Indonesia). He was married to Louisa Zecha, the Indo-Bohemian widow of Sim's former employer, Lauw Tek Lok, Luitenant der Chinezen of Bekasi. This was a senior civil government post in the Dutch colonial bureaucracy.

Together with his wife, Louisa Zecha, Sim settled down in Sukabumi, a hill station in the Preanger highlands of West Java. The sociologist Mely G. Tan calls Sim the most prominent of all of Sukabumi's Chinese headmen, in large part thanks to the high profile of his Eurasian wife. He died in 1906.

Kapitein Sim Keng Koen is the step-great-grandfather of the hotelier Adrian Lauw-Zecha, the founder of Aman Resorts, and the grandfather of the ballerina Che Engku Chesterina, a princess by marriage of Negeri Sembilan in Malaysia.
