Historical NoteReturn to Top

Ernest K. Lehmann was a professional geologist with experience in evaluation, exploration, development, and management of mineral deposit projects worldwide. He was born in Heidelberg, Germany on June 8, 1929, the youngest son of archaeologist Karl Lehmann and Elwine Hartleben. In 1935, the family immigrated to the United States. Lehmann graduated from Williams College in Massachusetts in 1951 and did graduate work in geology at Brown University from 1951-1952. Lehmann began his career as a miner and then geologist at a gold mine in Bannack, Montana before joining Kennecott Copper in Missouri. In 1958, he founded Ernest K. Lehmann & Associates, Inc., a consulting firm that provided reports, studies, and proposals regarding exploration, development, and management of mineral deposits such as copper, gold, limestone, and fluorspar worldwide. He was the president and CEO of Beaver Bay Inc., which owned an interest in the Twin Metals Minnesota coper-nickel project in the Duluth Complex and president of North Central Mineral Ventures Inc. He was also active in the Society for Mining, Metallurgy and Exploration and the American Institute of Professional Geologists.
