Michael George Lyme 'Gus' Mills (1946 – 2026)
It is with great sadness that St John's College shares the passing of Gus Mills (Alston 1963) on 12 July 2026. Involved in many aspects of wildlife conservation and seen as one of Africa's foremost experts on wild carnivores, he was a dedicated, influential scientist, gifted storyteller, and an accomplished photographer. Dr Mills received the St John's College Golden Eagle Award in 2023 during the College's 125th anniversary celebrations for his contribution to South African conservation and wildlife.
Although he described himself as a 'poor student', Dr Mills was highly regarded during his time at St John's College, playing for the First XV rugby and the First XI cricket, in which he achieved full and half colours respectively. Notably, he didn't study Biology at the College, although this field would become his calling. He was a house prefect for Alston and served as the Regimental Sergeant Major in the College Cadets, as well as singing in a student-led College jazz band, The Mirages. He showed a zest for life as a student and was not afraid to voice his opinions. These early leadership roles foreshadowed his pioneering spirit, a lifelong dedication to the conservation of wildlife, and his emergence as a frontrunner in his field.
Over the years, he contributed to improved national park management, spurred a "citizen science" movement in South Africa, and mentored a new generation of scientists. Through his extensive writings, talks, interviews, and involvement in documentary films, Dr Mills made an invaluable contribution to natural history, science, and education.
Dr Mills played a pivotal role in shaping the management of the Kruger and Kgalagadi National Parks, helping to introduce more ecosystem-based conservation practices, including ending elephant culling in the Kruger. An internationally respected scientist, he served as an Extraordinary Professor at the University of Pretoria, supervised numerous postgraduate students, and was a research associate at Oxford University. He founded the Endangered Wildlife Trust's Carnivore Conservation Group, published more than 150 scientific papers and several influential books on African carnivores, and initiated one of South Africa's earliest citizen science programmes to monitor wild dogs and cheetahs. His contributions were recognised with the Southern African Wildlife Management Association's Wildlife Excellence Award in 2016. Even in later life, Dr Mills continued to inspire, becoming the oldest person to climb Africa's third-highest peak, Margherita Peak, in Uganda's Ruwenzori Mountains, at the age of 80.
Dr Mills will be remembered at St John's for his life of service and the indelible mark he left on his field of study, as well as on a community of colleagues, students, and conservationists around the world.
Our thoughts and prayers go to his wife, Margie, and their children, Michael and Debbie.
