About John Crawfurd (from Wikipedia):
Dr John Crawfurd FRS (13 August 1783 – 11 May 1868) was a Scottish physician, colonial administrator and diplomat, and author. He is now best known for his work on Asian languages, his History of the Indian Archipelago, and his role in founding Singapore as the last British Resident of Singapore; the position of Resident was replaced by the Governor of the Straits Settlements.
Crawfurd was appointed British Resident of Singapore in March 1823. He was under orders to reduce the expenditure on the existing factory there, but instead responded to local commercial representations, and spent money on reclamation work on the river. He also concluded the final agreement between the East India Company, and Sultan Hussein Shah of Johor with the Temenggong, on the status of Singapore on 2 August 1824. It was the culmination of negotiations started by Raffles in 1819, and the agreement is now sometimes called the Crawfurd Treaty. He also had input into the Anglo-Dutch Treaty of 1824 dealing with spheres of influence in the East Indies.
Crawfurd was on familiar terms with Munshi Abdullah. He edited and contributed to the Singapore Chronicle of Francis James Bernard, the first local newspaper that initially appeared dated 1 January 1824. Crawford Street and Crawford Bridge in Singapore are named after him.
