Brief Biography of Tan Oo Long

Tan Oo Long was the second son of Tan Guat Teong, who emigrated from China to Malacca at a young age. Guat Teong's father, Tan Leong, tragically passed away in 1758 in Haiteng, China, at the age of 36, leaving behind his wife, a 3-year-old son named Guat Teong, and a daughter.

Born in 1755, Guat Teong settled in Malacca from an early age. There, he married Kow Geok Neo, who was 16 years his junior and hailed from a large family in Malacca, in contrast to Tan Guat Teong's smaller family.

Tan Guat Teong lived a long life, passing away in 1849 at the age of 85. He was buried in Malacca. His son, Tan Tock Seng, died the following year in Singapore, and Guat Teong's wife, Kow Geok Neo, passed away in 1851 on the eighteenth day of the eighth lunar month.

Upon Kow Geok Neo's death, her surviving elder son, Tan Oo Long, became the sole executor of her will, as the eldest son, Meng Long, had died much earlier at sea.

Tan Oo Long was a member of the Keng Teck Whay, a mutual aid organization consisting of 36 Hokkien businessmen who had come to Singapore. Many of these 36 individuals became pioneers in the early business scene of Singapore and Malacca.

Together with his brother Tan Tock Seng, Tan Oo Long invested in properties. Their names were recorded as registered landowners as early as 1827, just eight years after Sir Stamford Raffles founded modern Singapore.

Tan Wee Chuan was another son of Tan Swee Guan .  He was staying at 40 Outram Road , area 43,496 sq ft , which was auctioned off shortly after 


In 1850, a plaque commemorating the construction of the Tian Hock Keng temple recorded Tan Oo Long as paying interest of $49 to the temple. He probably would have take a loan from the temple fund ..  His brother, Tan Tock Seng, was known as a great contributor to the temple.
