Ernest Oberholtzer

Who was Ernest Oberholtzer?

Ernest Carl Oberholtzer was an American explorer, author and conservationist.

Nicknamed "Ober", he was born and raised in Davenport, Iowa, but he lived most of his adult life in Minnesota. Oberholtzer attended Harvard University and received a bachelor of arts degree, but left after one year of graduate study in landscape architecture. He made his first trip to the Minnesota-Ontario border lakes in 1906.

In 1909 he took his first extended canoe voyage through the border lakes and the Rainy Lake watershed, traveling 3,000 miles that summer. During the period from 1908 to 1915, Oberholtzer wrote a number of articles and short stories, some under the penname Ernest Carliowa. Many of the stories and articles were based on his canoe trip experiences. In 1913, Oberholtzer moved to Rainy Lake. He purchased Mallard Island in 1922; the tiny island would be his home for more than 50 years.

After plans were announced by business mogul Edward Backus to construct a series of dams to harness the Rainy Lake watershed for power generation, Oberholtzer spoke in opposition at a hearing of the International Joint Commission held at International Falls in September 1925.
