The wife of judge and politician Albert Bathurst Piddington, and related to Australian literary and political figures, she promoted ideas of racial hygiene and single mothers through association with several organisations and progressive movements.
[3] A theme in Piddington's campaigns was promotion of "celibate motherhood", unwed mothers receiving artificial insemination from a selected donor, in part to compensate for loss of suitable partners in the Great War.
She corresponded on the topics regarding the prevention of pregnancy and sexual transmission of disease, abortion and feminism and the contentious theories of social reformation emerging in Britain, Europe and the United States during the interwar period.
Her own papers include a response from Sigmund Freud to her proposals, polite but dismissive of her ideas for single mothers and foresaw disastrous consequences in the absence of sexual relations.
In 1916 she had published her adaptation of the ideas founded in eugenics, perhaps in response to the 1912 conference in London, Via Nuova; or Science and Maternity, a story or parable of a woman left without a suitable partner by the gender imbalance of young men lost in war.
