Leopold Archives

They provide a detailed look at the growth of the conservation movement from the early 1900s through Aldo's death in 1948 and beyond.

Explore Aldo's Legacy

In 2007, the Aldo Leopold Foundation and the University of Wisconsin-Madison Archives received a grant from the National Historic Publications and Records Commission (NHPRC) to digitize Leopold’s collected papers and photographs. Today, both the in-person and digital versions of the collection are available by request to conservation enthusiasts and casual learners alike.

Historical Treasures

The Collections

The wealth of knowledge that is the Aldo Leopold Archives is thoughtfully divided into two distinct collections: photographs and papers. The photograph collection was captured by Aldo’s son Carl, providing a visual journey through history. Meanwhile, the papers collection comprises a vast array of Leopold's writings, notes, and correspondence. These papers reflect the most advanced thinking and innovative practices across the spectrum of natural resource conservation, policy, and management during the first half of the 20th century. Together, these collections provide a comprehensive picture of the enduring impact Aldo and his family have had on conservation.

After a trip to Germany in 1935 to study European forestry methods, Leopold returned home with a Zeiss camera, which he gave to his son Carl. Acting as the family photographer, Carl quickly began documenting much of the family’s activity at the Shack in the 1930s and 1940s. The Leopold Foundation maintains Carl’s photographs in an archive that includes more than 1000 images.

Aldo was a meticulous and disciplined writer who kept extensive files of important correspondence, memoranda, reports, and related materials – all while publishing more than 500 articles, essays, and reports. This invaluable archive also contains over 500 more unpublished essays, reports, and other writings.

The collection includes Aldo's detailed journals of his Forest Service activity, travels, and hunting and field experiences, as well as observations and activities at his Sand County farm. His correspondence with his many graduate students and hundreds of leaders across a range of scholarly disciplines, professional fields, government agencies, and conservation organizations is also preserved.
