Nelly Hooper Ludbrook

Nelly Hooper Ludbrook (1907–1995) was an Australian geologist and paleontologist.
Nelly Hooper Woods (or Nell Hooper Ludbrook as she was known after her marriage) was born in Yorketown, South Australia on June 14, 1907. Her mother had studied as a teacher at the University of Adelaide in 1900. After attending Mount Barker High School, Woods enrolled in the University of Adelaide in 1926, taking her B.A. in 1928 and a teaching degree, as she had not studied enough prerequisite science subjects to enrol in a B.Sc.. She studied geology and mathematics, and appealed to Dr C.T. Madigan to give her a research project in geology. She worked on the fossil mollusc collection of Sir Joseph Verco for many years and pursued her M.A.

While working as a teacher at Mount Barker High School, Woods wrote a paper on Cainozoic molluscs, which was rewarded with the Tate Memorial Medal from the University of Adelaide in 1931. Woods married Dr Wallis Verco Ludbrook, who she had met at the University of Adelaide where he was studying his B.Sc. and she her B.A., in 1935, and they moved to Canberra. Irene Crespin, palaeontologist with the Commonwealth government, moved from Melbourne to Canberra, and employed Ludbrook as an Assistant Geologist from 1942-1949, working on the statistics of minerals for the war effort for the Department of Mines.

In 1950, Ludbrook travelled to England to study molluscs at the Imperial College of Science at the British Museum (Natural History), while her husband was away for work. Wallis Ludbrook died in 1951, and Nell was encouraged by her husband's family to remain in England and take her PhD in Pliocene molluscs of the Adelaide plains, at the University of London. After graduation in 1952, Ludbrook returned to Australia and began work as a Technical Information Officer for the South Australian Department of Mines. She was promoted to palaeontologist in 1957 and later senior palaeontologist, continuing in this role until her retirement in 1967. She was the Australian correspondent to the journal, Micropalaeontology from 1962-1966.

Ludbrook worked as a consultant in palaeontology for the South Australian Department of Mines after her retirement, describing Tertiary molluscan fauna. She also wrote, Handbooks of the Flora and Fauna of South Australia and Guide to the Geology and Mineral Resources of South Australia.

Ludbrook died in 1995. She has been praised for the way that she showed that paleontology could be useful to the resources industry. The P. Ludbrookiae zone in the Eromanga and Surat basins is named for her.

Seventeen fossil species were named for her including, Ludbrookia Chavan, 1951. She published over 70 scientific papers and monographs. She was appointed Member of the Order of the British Empire in 1981, for service to science.

The Geological Survey of South Australia named their fossil collection, the Ludbrook Library, within their geoscience laboratory in her honour.

Ludbrook was the first female President of the Geological Society of Australia in 1968. She was the first female president of the Royal Society of South Australia in 1961. She received the Sir Joseph Verco medal from them in 1963.
