Struan Sutherland (1936-2002) was the doyen of medical research in the field of envenomation and the ultimate authority on the medical management of envenomated victims in Australia for almost 3 decades. In 1981 as Head of Immunology Research of Commonwealth Serum Laboratories (CSL), he produced an antivenom against the Sydney Funnel-web Spider (Atrax robustus)-an accomplishment that had defied numerous previous attempts. Struan also invented the pressure-immobilisation technique of first-aid for snake bite. This ingenious, simple but safe and effective technique revolutionised first-aid management of snake bite and of some other types of envenomation. It made redundant the use of tourniquets and other dangerous first-aid treatments. Similarly, he helped to develop a snake venom detection kit, which enables doctors working at a victim's bedside to ascertain which snake was responsible and which antivenom should be administered. He had a very wide range of research interests and was a prodigious researcher publishing over 200 scientific and medical articles, numerous chapters in books and the standard Australian medical textbook on the management of envenomation, Australian Animal Toxins. He made major contributions to the understanding of the venoms of Australia's remarkable range of fauna including snakes, spiders, Blue-ringed octopus, ants, jellyfish and stinging fish. Struan served the medical fraternity and the public selflessly. He was always available to doctors, or to anybody, to give advice at any hour of the day or night, on management of envenomated victims. Members of the Australian Venom Research Unit, which he founded in 1994 at The University of Melbourne, now continue this 24-h advisory service.
