De Jongh family residence, 2 Chatham Road, Hong Kong; Kowloon Signal Hill, 1930

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.
 
Charles' colleague Frans de Jongh started much earlier at Holland-China Trading Company, in 1919, twenty years before Charles did. In 1930 he worked for the HCHC Hong Kong office. With his wife he lived at 2 Chatham Road, where their daughter Anneke was born, in the same year.

Flickr member Peter Heindl commented: "This is signal hill at Kowloon. The tower in the background is the signal tower. 1927 the upper part with the round windows was added. The thing on top is the „time ball“ which signaled noontime for the ships and replaced the noontime canon."
