Remembering two pioneers of wildlife biology

John Craighead, legendary wildlife conservationist and longtime member of The Wildlife Society, recently died just weeks after turning 100. He was considered one of America’s leading scientists, and perhaps best known for his research on grizzly bears in Yellowstone including his — and his late twin brother Frank’s — early use of radio collars to track the animals. Their 12-year study of the bears in and around Yellowstone National Park resulted in the listing of the species as federally threatened, which ultimately helped save the bears from extinction in the lower 48 states. In 1998, John received the Aldo Leopold Award — The Wildlife Society’s highest honor for excellence in the field of wildlife conservation.
