Johann Menge

Johannes Menge (4 January 1788 – 1852), has been regarded as South Australia's first amateur geologist. An early explorer of the new colony, he was influential in the settlement of the Barossa Valley. He has sometimes been given the title, father of South Australian mineralogy.

Born in the town of Steinau, Hesse, Germany, Menge had little formal education, but was a keen learner and quickly gained a broad knowledge of languages, philosophy, medicine, religion, and geology. His particular interest in geology developed after his early employment by Privy Councillor Karl Cäsar von Leonhard, who collected and sold mineral specimens. Menge later travelled widely through Europe and beyond, and was awarded an honorary degree of Professor of Mineralogy from the University of Lubeck in 1821.

After the death of his wife in 1830 he moved to England and taught languages. Here he became friends with George Fife Angas, who encouraged him to travel to the new colony of South Australia for employment with the South Australia Company. Menge sailed to South Australia aboard the Coromandel, arriving on Kangaroo Island on 12 January 1837, where he was hired as the colony's Mine and Quarry Agent and Geologist. However, his eccentric ways soon led to his dismissal from the company on 30 June 1838.

Menge then moved to the South Australian mainland, travelling widely, exploring and searching for minerals in his own right, while engaging in many other interests. He travelled as far north as Mount Remarkable. He was the first to discover copper in the Adelaide Hills. He kept in regular contact with George Fife Angas and sent him letters and reports; his activities thus encouraging the spread of settlement, and mineral exploration by others. This ultimately led to a mining boom that saved the fledgling colony. He wrote papers on several topics, particularly mineralogy, and in 1840 wrote a book entitled Mineral Kingdom of South Australia.
