J. H. Curle

James Herbert Curle (18 October 1870 – 26 December 1942) was a Scottish mining engineer, traveler, writer, eugenicist, and philatelist. He wrote ''The Gold Mines of the World'' as well as autobiographical and travel works of a philosophical turn.

He was a member of the Eugenics Society and published ''To-day and To-morrow: The Testing Period of the White Race'' (1926) in which he surveyed the races of the world and argued that the white race was being out-bred by other races and its purity being eroded through inter-breeding with other races.

He won awards for his collection of stamps of the Transvaal and in 1940 jointly won the Crawford Medal of the Royal Philatelic Society, London, for his book on the postage stamps of that province. Provided by Wikipedia
