Karl Friedrich August GüTZLAFF (aka Charles Gutzlaff) [1803-1851]
Karl Friedrich August Gützlaff was a German Lutheran missionary, the first one in China.
He was sent by the Netherlands Missionary Society to Java in 1826, where he learned Chinese. Later he went to Singapore and Bangkok. From about 1830 he worked in Macau, and a bit later in Hong Kong where he worked on a Chinese translation of the Bible.
He also worked as an interpreter, first for William Jardine, later for the British government during negotiations during the First Opium War (1839-1842).
