Doug Waterhouse was a renowned entomologist, a fine scientist and an accomplished administrator. He worked within the Commonwealth Scientific Industrial Research Organisation (CSIRO) Division of Entomology for over 60 years, and was its Chief for 21 years until his retirement in 1981. Doug was responsible for many developments in insect and weed control, both in Australia and around the globe, especially in developing countries across Asia and the Pacific. He not only guided the Division to international prominence, but was also an ardent humanitarian whose work had beneficial effects in many neighbouring countries. Much of his ‘public good’ work was done as an Honorary Fellow (1981–2000). As well as his extensive entomological interests, Doug was active in other areas such as education and community services. He was the foundation Chairman of the Canberra College of Advanced Education and continued as Chancellor when it became the University of Canberra.
