The Australian National University has paid tribute to Joan Duffield and her legacy as a philanthropist supporting astronomy research at the Mount Stromlo observatory in Canberra.
Duffield died at an aged care home at Malvern in Melbourne on 1 November, aged 104.
She was the daughter of Walter Duffield, a South Australian astronomy professor who lobbied state and federal governments for 18 years to build a solar observatory in Canberra. In 1924, he became inaugural director of the Solar Physics Observatory at Mount Stromlo and held the post until his death in 1929.
