Khouw Tjeng Tjoan

Khouw Tjeng Tjoan, Luitenant-titulair der Chinezen (Chinese: 許清泉; pinyin: Xǔ Qīngquán; died in 1880) was a Chinese-Indonesian magnate and landlord.

Born into the Khouw family of Tamboen, he was the oldest of the three sons of the landlord and magnate Luitenant Khouw Tian Sek (died in 1843). From the mid-nineteenth century until his death, the younger Khouw and his brothers, Luitenant Khouw Tjeng Kie and Luitenant Khouw Tjeng Po, were widely acknowledged as the wealthiest Chinese in their native hometown of Batavia (now Jakarta, capital of Indonesia). He was a generous philanthropist, and was raised in 1856 to the honorary rank of Luitenant-titulair der Chinezen, but without any of the entailed responsibilities in the civil administration.

Luitenant Khouw Tjeng Tjoan lived with his wife, ten concubines and twenty-four children at Candra Naya, one of the three mansions on Molenvliet belonging to the Khouw family of Tamboen. His funeral in 1880 attracted - according to the newspaper Bintang Barat (November 17, 1880) - thousands of onlookers who thronged the whole stretch of Molenvliet, all the way to Kebon Jeruk.

Six of the Luitenant's sons served as Chinese officers in the colonial bureaucracy, most notably Khouw Kim An, the fifth and last Majoor der Chinezen of Batavia.
