Following completion of his PhD from the University of Sydney in 1960, Bruce Sheldon was employed by CSIRO Division of Animal Genetics as a Poultry Research Scientist at Werribee in Victoria. He progressed to Chief Research Scientist in 1992 and was Leader of the Poultry Genetics Unit at CSIRO from 1965 to 1994 when he retired.
Over the years he and his team of researchers at CSIRO published extensively on layer genetics and reproductive physiology in general and more specifically on selection to reduce the interval between eggs within a clutch and on triploid intersexes and sex determination in chickens. By the early 1990s, his group at CSIRO was at the forefront of world research in developing novel technologies for molecular genetic engineering in poultry. He received the Australian Poultry Award in 1992 and was invited that year to join the International Standing Committee on Poultry Genome Mapping. He was President of the Australian Branch of WPSA from 1982 to 1992, a Vice-President of the WPSA World Body from 1984 and Senior Vice-President from 1996 until his passing. During his time on the WPSA World Body he was a staunch advocate for the promotion of poultry research, development and education in developing countries. Bruce Sheldon passed away at 73 years of age in Sydney in April 2003. He is sadly missed by his friends and colleagues.
