Iain Douglas-Hamilton (died December 8th 2025, aged 83) was a Scottish-born zoologist and conservationist who devoted his life to studying and saving African elephants. He was the grandson of a Scottish duke and the son of a second-world-war Spitfire pilot.
Dr Douglas-Hamilton read zoology at Oxford under Niko Tinbergen, one of the founders of ethology—the study of animal behaviour in natural settings, as opposed to the laboratory-based "behaviourist" approach of B.F. Skinner at Harvard. He arrived in Tanzania in 1965, part of a generation of field zoologists that included Jane Goodall (chimpanzees), Dian Fossey (gorillas), George Schaller (lions) and Hans Kruuk (hyenas). Elephants were as yet unclaimed; he made them his own.
Working initially with field-glasses and a notebook, he came to know individual elephants and their particular quirks. He later added a Cessna to his inventory, flying low and slow to log every individual, from the smallest calf to the biggest bull, using the transect approach pioneered by earlier ecologists. Applied across Africa, this aerial census method revealed the scale of damage done by ivory poachers.
His censuses showed Africa's elephant population crashing from 1.3m in 1979 to 600,000 in 1989. He testified several times before America's Congress in the 1970s and 1980s, helping to secure the passage of the African Elephant Conservation Act in 1988. In testimony in 2012 he described how poachers linked to rebels in Darfur had travelled over 1,000 miles on horseback and massacred more than 400 elephants in Cameroon.
After the fall of Idi Amin in 1979, Dr Douglas-Hamilton was invited to become honorary chief warden of Uganda's three national parks in 1980. He organised air and ground patrols to fight poaching gangs operating from neighbouring Sudan, some of whom tried to shoot down his plane. He helped raise the country's elephant population from a few hundred to several thousand.
In 1993 he and his wife Oria founded Save the Elephants, based in Samburu National Reserve in Kenya. The organisation monitors about 1,000 elephants, often using satellite-monitored radio collars. Across Africa, elephant populations rose in Botswana, Namibia, South Africa, Kenya, Tanzania, Angola and Zimbabwe, though poaching pressure shifted to forest elephants—recognised as a distinct species since 2021—whose population fell by 86% in the 31 years before that recognition. About 400,000 African elephants remain between the two species.
Dr Douglas-Hamilton championed the use of bee fences—hives placed at regular intervals along farm perimeters—to deter elephants from raiding smallholdings without harming them. By 2024, more than 14,000 hives had been deployed by farmers in Africa and Asia. It was an attack by a swarm of bees in February 2023 that ultimately led to his death; he threw himself over his wife to shield her but never fully recovered from the resulting anaphylaxis.
Soap and education are not as sudden as a massacre, but they are more deadly in the long run.
