Ainslie Roberts (12 March 1911 – 28 August 1993) was an Australian painter, photographer, and commercial artist. He is best known for his interpretations of Aboriginal legends in his Dreamtime books, written in collaboration with ethnologist/anthropologist Charles Mountford. The bestsellers The Dawn of Time (1969), The First Sunrise (1971) and a larger edition The Dreamtime Book (1973) were all published before Mountfords death in 1976. The journalist Douglas Lockwood replaced Mountford on subsequent trips and he and Roberts would collaborate on Dreamtime Heritage (1975), Dreamtime: the Aboriginal Heritage (1981) and Echoes of the Dreamtime (1988) were published with contributions from the Roberts, Lockwood and Mountford families.
