Born in central Thailand's Pichit province to a Chinese father and a Thai mother who reportedly sold fruit and ducks to survive:
- Mr Chaleo died the third richest man in Thailand
- He started a small company, TC Pharmaceuticals, in the 1960s
- He formulated an energy drink prototype a decade later called Krathing Daeng, or Red Bull
