Robert Dessaix was born in Sydney and adopted at an early age. His interest in Russian literature led him to study in Moscow during the late 1960s and early 1970s. Upon gaining his PhD, Dessaix changed his surname from 'Jones' (the name of his adoptive parents) to 'Dessaix' (the name of his biological parents). After teaching Russian language and literature at the University of New South Wales and the Australian National University for almost twenty years, Dessaix began a career as a writer, reviewer and broadcaster.
Beginning in 1985, Dessaix produced and presented the ABC Radio program "Books and Writing" for ten years. Since the early 1980s, his reviews and short stories have appeared in a variety of journals and newspapers and he has edited several anthologies, including Australian Gay and Lesbian Writing (1993). He has published translations, collections of prose and novels, winning several awards in the late 1990s. Dessaix's widely-admired autobiography, A Mother's Disgrace (1994), recounts the search for his birth mother and the discovery of his sexuality, explaining the development of his personal philosophy.
Robert Dessaix lives in Tasmania. He is a regular speaker at writers' festivals, but regards himself as a dilletante rather than a public intellectual.
