Henrietta Drake-Brockman, née Jull, was born in Perth, Australia. Her parents were Martin Edward Jull, an English-born public servant, and his Scottish-born wife Roberta, a medical practitioner. Henrietta was educated at boarding school in Scotland and at Frensham School for girls in Mittagong, New South Wales. She studied literature at the University of Western Australia and art in Henri Van Raalte's Perth studio. In 1921, at age 20, she married Geoff Drake-Brockman, then Commissioner for North-West Australia, and accompanied him on his work travels. Both she and her husband wrote articles about their trips for The West Australian, and these journeys also became source material for her novels. By 1926, she had established her reputation as a writer. Some of her works were published under the pseudonym "Henry Drake." Her novels included Blue North (1934), Sheba Lane (1936), Younger Sons (1937) and The Fatal Days (1947). Her last novel, The Wicked and The Fair (1957), centred on the voyage of the ship Batavia, which ran aground off the coast of Western Australia in 1629. Her last book, Voyage To Disaster (1963), was a biography of Francisco Pelsaert, commander of the Batavia. In 1963, she became one of the four acknowledged co-discoverers of the Batavia wreck off the Abrolhos Islands. She also wrote plays, some of which were staged, including The Man from the Bush (1932), Dampier's Ghost (1934) and The Blister (1937). Her best-known play, Men Without Wives, was published in 1955.
