Born in Batavia, Lauw Tek Lok was the son of the early nineteenth-century tycoon Lauw Ho (died in 1863), part of the powerful Ngo Ho Tjiang opium partnership.[5][6] His father was an important revenue farmer, and served as Wijkmeester (ward master) of Meester Cornelis.[7][5] The younger Lauw became one of the most important landlords ('Landheeren') in Batavia with significant agricultural landholdings ('particuliere landen') in the city's Ommelanden (the then rural hinterland of Batavia), including the estate of Cimanggis.[8]
Lauw was appointed on December 23, 1854 to the newly created government post of Luitenant der Chinezen of Bekasi, a civil administrative position he would keep until his death in 1882.[9][2] At the same time, his brother Lauw Tek Kang was also raised to the post of Luitenant der Chinezen of Meester Cornelis.[9] As Luitenant, Lauw Tek Lok played a significant role in the Dutch colonial development of Bekasi and its surrounding region. On his death in 1882, Lauw was succeeded as Luitenant der Chinezen of Bekasi by another local landlord and his son-in-law, Tan Kang Ie.[10][11]
Despite his satisfactory records as a colonial administrator, Lauw caused some consternation among the colonial authorities due to his unconventional and interracial marriage with an Indo woman of Bohemian descent, Louisa Zecha.[4][1] Together, they became the ancestors of the prominent Lauw-Sim-Zecha family, and were the great-grandparents of Adrian Lauw Zecha, founder of Aman Resorts.[12]
