The Frank Craighead Grizzly Materials Digital Collection

What is it?

This collection contains the collected research of Dr. Frank C. Craighead Jr. (1916-2001), a scientist and naturalist. He is best known for his studies of grizzly and black bears in Yellowstone Park with his twin brother John Craighead, which were done to learn about the animal's habits and movements. This long-term study led the brothers to develop the radio-tracking of wildlife to learn the bear's movements and habits, and how they interacted with and impacted the park. Papers and correspondence detailing this study, as well as photos and publications, make up most of the collection's contents.
