The Diethelm Keller Group’s origins date back to the 1860s when two Swiss pioneers ventured to the Far East: Wilhelm Heinrich Diethelm settled down in Singapore, while Edward Anton Keller went to the Philippines. The businesses set up by the two entrepreneurs developed over time into successful family enterprises. While the Diethelm Group was mainly active in Thailand, Singapore, Malaysia and Indochina, the business of the Edward A. Keller Group was concentrated in the Philippines, Korea, Hong Kong, China and Australia.
