4 April 1875
German explorer Karl Gottlieb Mauch, allegedly the first person to discover gold in South Africa, died in poverty in Stuttgart, Germany. He made geologic and archaeological discoveries in southern Africa, notably the gold fields in Hartley Hills in 1867 and the ruins of the ancient city of Zimbabwe. On his return to Potchefstroom, South African Republic, he announced that he had discovered a vast ancient gold field scarred with abandoned mine workings. He claimed that it was the legendary Ophir, mentioned by King Solomon and the Queen of Sheba. He won prizes for his gold and mineral specimens at the agricultural show, but he never discovered any payable deposits from his prospects.
