John Thomson (14 June 1837 – 29 September 1921) was a pioneering Scottish photographer, geographer and traveller. He was one of the first photographers to travel to the Far East, documenting the people, landscapes and artefacts of eastern cultures. Upon returning home, his work among the street people of London cemented his reputation, and is regarded as a classic instance of social documentary which laid the foundations for photojournalism. He went on to become a portrait photographer of High Society in Mayfair, gaining the Royal Warrant in 1881.
In April 1862, Thomson left Edinburgh for Singapore, beginning a ten-year period spent travelling around the Far East. Initially, he established a joint business with William to manufacture marine chronometers and optical and nautical instruments. He also established a photographic studio in Singapore, taking portraits of European merchants, and he developed an interest in local peoples and places. He travelled extensively throughout the mainland territories of Malaya and the island of Sumatra, exploring the villages and photographing the native peoples and their activities.
After visiting Ceylon and India from October to November 1864 to document the destruction caused by a recent cyclone, Thomson sold his Singapore studio and moved to Siam. After arrival in Bangkok in September 1865, Thomson undertook a series of photographs of the King of Siam and other senior members of the royal court and government.

Inspired by Henri Mouhot's account of the rediscovery of the ancient cities of Angkor in the Cambodian jungle, Thomson embarked on what would become the first of his major photographic expeditions. He set off in January 1866 with his translator H. G. Kennedy, a British Consular official in Bangkok, who saved Thomson's life when he contracted jungle fever en route. The pair spent two weeks at Angkor, where Thomson extensively documented the vast site, producing some of the earliest photographs of what is today a UNESCO World Heritage Site.
