David George Stead (6 March 1877 – 2 August 1957) was an Australian marine biologist, ichthyologist, oceanographer, conservationist and writer. He was born at St Leonards in Sydney, and educated at public schools and the Sydney Technical College. In 1909 he was a founder of, and during its early years the main driving force behind, the Wildlife Preservation Society of Australia. His career included many government positions both in Australia and in Malaya. He served as the Australian representative on international committees concerned with fisheries science, marine biology and oceanography. He married three times, the third time to botanist and writer Thistle Yolette Harris in 1951. He died at his home in Watsons Bay, Sydney.[1][2]
Stead is commemorated in the David G. Stead Memorial Wild Life Research Foundation of Australia, and the Wirrimbirra Flora and Fauna Sanctuary at Bargo, New South Wales, established by his third wife in his memory in the early 1960s. Mount Stead in the Blue Mountains is named after him. He was survived by two daughters and three sons of his second marriage and by the only child of his first marriage, the novelist Christina Stead.[1][2]
