Deborah Vernon Buller Murphy (née Drake-Brockman, previously Hackett and Moulden; 18 June 1887 – 16 April 1965), best known as Lady Hackett or Lady Moulden, was an Australian community worker, philanthropist, and mining investor.

[1] On 3 August 1905, at the age of 18, she married Sir John Winthrop Hackett (1848–1916), who was forty years her senior.

She died at her home, Lordello, (in Kilsyth, Victoria) on 16 April 1965 and was buried in Karrakatta cemetery, Perth.

[6] In 1923 she became interested in tantalite, a rare mineral found in the Northern Territory and at Wodgina in Western Australia.

The degree was awarded in absentia, being unavailable due to the recent death of Sir Frank Moulden.
