In his life, he held an important position in a bank. However, Tan Sri (Dr) Tan Chin Tuan who led and built the Oversea-Chinese Banking Corporation (OCBC) from 1966 to 1983 into one of the largest banks at that time, was always concerned about the lives of the less privileged and the disadvantaged. Tan Sri Tan’s collection of documents that was kept by Mr Tan’s family and the Tan Chin Tuan Foundation are now valuable resources for intellectuals and academic scholars who wish to research on Mr Tan’s personal life, as well as the history of Singapore’s economy in the early 1950s.
