Abstract
George Christian Hoffmann, of German extraction, was born in London. After studying at the Royal School of Mines and working in London as a chemical analyst, he set out on a career that took him to Natal, in south-east Africa, to Melbourne in the Australian colony of Victoria, and to Canada where he had a long career with the Geological Survey, becoming Deputy Director in 1880 and retiring in 1907. In his work with the Geological Survey, he determined the chemical composition and identity of mineral samples collected by and submitted to the Survey, assessing their economic potential.

Résumé
George Christian Hoffmann, d’origine allemande, est né à Londres. Il a étudié à la Royal School of Mines et a travaillé à Londres comme analyste chimique avant de se lancer dans une carrière qui l’a mené au Natal, dans le sud-est de l’Afrique, à Melbourne, dans la colonie australienne de Victoria, puis au Canada, où il a eu une longue carrière au sein de la Commission géologique du Canada (CGC); il en est devenu le directeur adjoint en 1880, et a pris sa retraite en 1907. À la Commission géologique, il déterminait la composition chimique d’échantillons minéraux recueillis ou reçus par la CGC et définissait ainsi leur identité, et en évaluait le potentiel économique.
