Hans Merensky

Hans Merensky (16 March 1871 in Botshabelo – 21 October 1952 on his farm Westfalia near Duiwelskloof) was a German South African geologist, prospector, scientist, conservationist and philanthropist. He discovered the rich deposit of alluvial diamonds at Alexander Bay in Namaqualand, vast platinum and chrome reefs at Lydenburg, Rustenburg and Potgietersrus, which led to some of the largest platinum mines in the world, phosphates and copper at Phalaborwa in the Transvaal lowveld, gold in the Free State and the world’s biggest chrome deposit at Jagdlust near Pietersburg.

Hans Merensky was born on 16 March 1871 at Berlin Missionary Society station Botshabelo, near Middelburg in Transvaal, where his father, Alexander Merensky (1837–1918), a noted ethnographer and author, was the resident missionary. Keenly interested in minerals and enjoying outdoor living, he studied mining geology after finishing his schooling in Germany. He was awarded a doctorate in mining geology from the University of Charlottenburg in Berlin. He completed his practical training in coal mines in the Saarland and in Silesia and began work for the Department of Mines in East Prussia. In 1904 he came to South Africa to conduct some geological surveys in the Transvaal. He discovered tin near Pretoria and reported to the Premier Diamond Mine regarding possible mining prospects. He worked for several mining companies and Friedlaender & Co. sent him to Madagascar to investigate a reported discovery of gold, which turned out to be false. He resigned from his job in Germany and moved to Johannesburg where he became a successful consulting geologist.
