Born in West Guildford, Western Australia, on 18 June 1887, she was the daughter of surveyor Frederick Slade Drake-Brockman and heroine Grace Vernon Bussell and younger sister of Edmund Drake-Brockman.
He was a newspaper proprietor, newspaper editor, and prominent Western Australian politician. Hackett senior died in 1916 leaving a large estate to his family, and a large endowment to the University of Western Australia. On 10 April 1918 Lady Hackett, now aged 30, married (Sir) Frank Beaumont Moulden and moved to Adelaide.
She was Lady Mayoress of Adelaide 1919-1921, and became Lady Moulden in 1922.
Moulden died after a cerebral haemorrhage on 8 April 1932. In 1923 Lady Moulden became interested in tantalite, a rare mineral found in the Northern Territory and at Wodgina in Western Australia.
Tantalite was scarce throughout the world, and the price of tantalum was enormous. She saw the wealth that it could bring to Australia, particularly if it was processed in Australia, but the government was not particularly interested in the idea.
She founded Tantalite Limited which was incorporated in 1932.
In World World War II her tantalum was used in developing radar. The need for it became so obvious to the previously reluctant Commonwealth government that it resumed Tantalite Limited for the duration of the war. In 1932, the University of Western Australia conferred upon her an honorary Doctorate of Laws.
The degree was awarded in absentia due to the recent death of Sir Frank Moulden.
He died 10 March 1963. She died at her home, Lordello, (in Kilsyth, Victoria) on 16 April 1965 and was buried in Karrakatta cemetery, Perth.
