Daisy Bates
Daisy Bates was a controversial and complex character, known for her contribution to Aboriginal welfare. She was a master at reinventing herself and creating opportunities where none previously existed.
She was a self-taught anthropologist and journalist who convinced the London Times to send her to Australia to investigate the ill-treatment of Aboriginal people. She arrived in Australia in 1883 'a strange kind of Mary Poppins figure with her carpetbag and her parasol and arriving daintily into [A]boriginal culture with a strange array of Victorian expectations about how they might live their lives' (Dr Philip Jones, Curator of SA Museum).
She conducted fieldwork amongst the Indigenous tribes in western and southern Australia recording information of their customs, mythology, language and lifestyle. Her collection in the South Australian Museum Archives contains some of this valuable data. However, Daisy never lived with Aboriginal people but camped alongside them. She lived on the fringes of Aboriginal society and of white society, seemingly never completely fitting into either. The Aboriginal people called her Kabbarli meaning 'grandmotherly person'.
Daisy supported herself by writing articles for the newspapers and it was in some of these articles that she took a less anthropological tone and exaggerated and sensationalised her stories to make them more attractive. In the 1920s, people in England and America were amazed to discover that the Aboriginal people (apparently) ate their babies. 
Some of the sources I read claimed she was a serial bigamist. Her first marriage was her most notable, to the legendary Breaker Morant.
She was awarded the Commander of the Order of the British Empire for Aboriginal welfare work in 1934. In her later years, she moved to this spot at Pyap, pitched her tent, set up her typewriter and wrote her autobiography 'My Natives and I'. She died in 1951 aged 91 years.
