As well as being an eminent and much-loved teacher of geology, his writings on the history of our science and the lives and achievements of the many pioneering geologists and explorers will always be seen as his most distinguished contributions. Early research for a doctorate on the coal seams in the Newcastle region led to the expansion of his nascent interest in the history of science and geology. David’s interest in the history of geology and science was enhanced further through his contact and friendship with INHIGEO Vice President, Tom Vallance. David began to attend the INHIGEO’s conferences contributing actively. He was INHIGEO President 1992–1996. He wrote around 20 books, and 230 papers and articles, about half of which have been dedicated to the history of geology, of mineral exploration, the history of ideas in science, as well as biographies of geologists, engineers, and metallurgists. His most important work was his definitive biography of T.W. Edgeworth David, described as a masterful work on an Australian pioneering geological academic and explorer. In 2007 David was awarded an honorary DSc. by the University of Sydney, chiefly in recognition of this biography.
He was a founding member of the Geological Society of Australia (GSA) in 1952, and the founding editor of The Australian Geologist in 1974, a role he held for 10 years. He received many honours and awards, including Honorary Life Membership of the GSA in 1992, the Royal Society of NSW Medal in 1998, and was the inaugural recipient of ESHG’s Tom Vallance Medal for contributions to Australian Earth Science History presented at the 34th IGC 2012. Other honours included the 2020 V. V. Tikhomirov Award for the History of Geology. In 2018 he was appointed as a Member of the Order of Australia (AM).
