Tan Sri (Dr) Tan Chin Tuan not only had a formidable reputation for business, he was also one of the island’s best-known philanthropists. Since 2005 the foundation bearing his name has been housed in the restored mansion and run by his family. His granddaughter, Chew Gek Hiang, estimates hundreds of millions of dollars have gone to charitable causes since 1976 when the foundation was first formed. She meets her siblings and her mother, who chairs the foundation, once a month in the mansion to seek consensus in deciding which projects to give to.
