Hetzel graduated in medicine from the University of Adelaide in the 1940s. He was held a Fulbright Research Scholar in the 1950s. He returned to Adelaide and was employed as Reader and then Michell Professor of Medicine at the Queen Elizabeth Hospital, Adelaide, University of Adelaide before moving to Monash University as the Foundation Professor of Social and Preventive Medicine. He also held the position of first chief of the CSIRO Division of Human Nutrition, Chair of the University of South Australia's Bob Hawke Prime Ministerial Centre, and University of South Australia Chancellor 1992–1998,
Hetzel worked in remote areas of Papua New Guinea with the Public Health Department of the then Territory, and his research concluded that the endemic goitre and associated cretinism was attributable to an iodine deficient diet. He also demonstrated that dietary supplementation would entirely prevent these illnesses.
In the 1980s Hetzel, supported by the Australian Agency for International Development, became an international advocate for iodine supplementation, which is now taken for granted with iodinated table salt. This was part of the stimulus for the creation of the International Council for Control of Iodine Deficiency Disorders association, which is funded by various government, non-government and community organisations including the United Nations, UNICEF, the World Health Organization, and the World Bank. It is claimed that iodine supplementation has been achieved in 70% of households worldwide by 2000.
Hetzel was Lieutenant Governor of South Australia from April 1992 - May 2000.[1]
