John Harfield Tredgold

John Harfield Tredgold (1798 – 22 May 1842) was an English chemist in the Cape Colony in Africa. He held a number of voluntary roles including Secretary of the British and Foreign Anti-Slavery Society. The suburb of Cape Town called Harfield drew its name from Tredgold's middle name.

Biography Tredgold was baptised in 1798 by his parents Thomas and Elizabeth Tredgold. His middle name was his mother's surname before she married 10 April 1795.

He is thought to have employed John Pocock, whose diaries give an insight into the Tredgolds' family life. Of particular note is a reference to an evening party in 1836 when letters were read from Richard Miles, "a Bechuana boy formerly in the employ of Mr T. but now an itinerant preacher to the native tribes beyond the border". Richard Miles was to go on to have an interesting career as a preacher and interpreter long after Tredgold had left the country. In 1850, Richard Miles was appointed Kaptyn of Bethanie, by the British Resident, Major Warden, in the name of His Excellency the Governor of the Cape.
