In the late 1860s, two young Swiss pioneers, Wilhelm Heinrich Diethelm and Edward Anton
Keller, ventured to the Far East. Diethelm settled in Singapore, while Keller chose the Philippines as his new home. They found employment and soon set up their own businesses trading to and from Europe.
Over time, the descendants of the founding families substantially expanded the trading business into marketing, logistics and related services, while also diversifying into industrial and travel activities.
