This Collection (1917-1977) focuses on the working papers of Robert Hoffman, mining engineer and geologist. It includes documents, correspondence, reports and field journals, but also scattered photographs and personal materials.
Hoffman started his career during the 1920's Canadian "gold rush" as a young man, and worked other sites in Canada including the Sunset Yellowknife mines, Northwest Territories. He invested in or owned a number of mining companies in both the US and Canada, and was president of Quebec Cobalt Mining and Exploration Ltd. and Towne Mines Inc. Hoffman gifted Harvard University with the David and Arnold Hoffman Memorial Building for Experimental Geology in honor of two brothers.
