Sir T. W. Edgeworth David

Died 28 Aug 1934 at age 76 (born 28 Jan 1858).Tannatt William Edgeworth David was a Welsh-Australian geologist who produced an extensive study of the geology of Australia, including the first geological map of the Sydney-Newcastle Basin. He also researched the evidence of major glaciations in Australia of the Upper Paleozoic time (from 345- to 225- million years ago). In 1897, he drilled to a depth of 340-m at Funafuti Atoll in an effort to verify Darwin's theory of the formation of coral atolls. Whereas his results supported Darwin's ideas, they were short of absolute proof. He served as scientific officer of the Shackleton Antarctic Expedition from 1907-9, and led the party that first reached the southern magnetic pole on 16 Jan 1909, which was on land at that time.«
