Charles Gesner van der Voort had started his career in Rotterdam, at Holland-China Trading Company (HCHC). In 1938, he went to Shanghai for the firm. The Japanese interned him, and most other Dutch nationals, from 1943-45. In camp, he met his wife Nancy and they married after the war. After a leave in The Netherlands, they returned to the Orient, where Charles continued to work for HCHC in Hong Kong.
