Reg Sprigg

Reg Sprigg died on 2 December 1994 whilst on holiday in Glasgow, Scotland. His ashes were scattered at Arkaroola.

In 1968, Sprigg purchased the pastoral lease of Arkaroola, a property and important uranium exploration field of 610 square kilometres in the Flinders Ranges of South Australia, and converted it into a wildlife refuge and tourist attraction. A governing board of Reg Sprigg, his wife Griselda and Dennis Walter, a mineralogist and old friend, oversaw the creation of Arkaroola Village out of existing buildings and the opening to tourists in October 1968.

In 1962 Geosurveys became incorporated into Beach Petroleum, of which Sprigg was General Manager.

Griselda and the children often accompanied Reg in his outback travels. In 1962 the entire family completed the first vehicular crossing of the Simpson Desert. In 2001, Griselda published an account of those travels in Dune is a four-letter word.

Of other significance, Sprigg helped establish Santos (an acronym for South Australia Northern Territory Oil Search), which discovered gas deposits in Cooper Basin, including the Moomba Gas Field, which supplies natural gas to South Australia, New South Wales and Canberra. In 1954 Sprigg formed the company Geosurveys of Australia, which was a consulting and contracting company for geological and geophysical work. They prospected for uranium in the Northern Territory and nickel in the north west corner area of South Australia as well as working for Santos.

In 1952, a daughter, Margaret and in 1954, a son, Douglas were born in South Australia.

On 3 February 1951, Sprigg married Griselda A. Findlay Paterson, daughter of Robert Findlay Paterson and Grace née Dreghorn, born December 1921 in Paisley, Scotland. Griselda had studied in Glasgow and qualified as a radiographer.

Sprigg attracted the attention of the Australian Security Intelligence Organisation (ASIO) in 1950, due to Sprigg's knowledge of uranium deposits in Australia and throughout the world. In 1943 Sprigg had been secretary of the Australian Association of Scientific Workers. The association was concerned with the transfer of scientific workers from wartime to peacetime projects once hostilities ceased, and encouraged debate on the social responsibility of science. ASIO suspected the organization of communist ties, and as a result Sprigg was surveilled for some ten years.

In 1942, Sprigg married Patricia Day who had been born in Wiltshire, England and relocated to Adelaide with her parents in 1927. In 1943, she graduated as a BA (Adelaide), scoring first place in Political Science and worked in the History School during 1945 and 1946 reading essays and lecturing. In 1948, Patricia, aged 25, left Adelaide on the P&O ship SS Stratheden, arriving in London on 27 March 1948. In London she worked at Magazine of the Future whilst reading law at Lincoln's Inn. Reg and Patricia divorced in 1950 and she moved to Sweden in 1951 to marry Gillis Een.

During 1948, Reg, still with the South Australian Mines Department, was in Britain in association with uranium on behalf of the government; Griselda has said that she met Reg "on ...the island of Arran, .... Well there was I with three nursing sisters I’d held up with, and as I walked out of the restaurant that night, they stopped me and said, 'I bet you can’t get a date with the Australian before midnight tonight, for tomorrow. I said 'How much is it worth', they said 'five quid', and I said 'that’ll do me'. I got the five quid, got the date, and I always say, I won him in a bet."

Sprigg was sent by the South Australian government in 1946 to inspect abandoned mines in the Ediacaran Hills, to ascertain whether old mines could be reworked profitably using new technologies. When he discovered the fossils, apparently while eating his lunch, he realised that they were very ancient, either of Early Cambrian, or possibly even of Precambrian age. He thought that the organisms had probably been jellyfishes. He submitted a paper to the journal Nature, but it was rejected. He travelled to London and presented his findings to the 1948 International Geological Congress, but failed to excite either interest or belief. Subsequent work by Prof Martin Glaessner at the University of Adelaide demonstrated that they were indeed of latest Precambrian age. Although Precambrian animal fossils had been reported before, they had not been accepted universally as organic. This discovery resulted ultimately in the definition in 2004 of the Ediacaran Period, the first new geological period created in more than one hundred years.

Sprigg next worked for the South Australian Geological Survey, which sent him to reopen the Radium Hill Uranium Field in 1944, and to map the Mount Painter uranium field. At the time, uranium was believed to be rare, and was required for the Manhattan Project.

At the University of Adelaide, he was a pupil of Sir Douglas Mawson who said that "Sprigg was his best-ever student". He completed the requirements for his Bachelor of Science and then graduated Master of Science in 1942.

In 1940 he enlisted in the Royal Australian Engineers, and worked with Munitions from 1941 to 1942. He transferred to work with the soils division of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) until 1943.

He matriculated from the Adelaide Technical High School in 1938.

In addition to pursuing his studies in geology, Reg developed drawing skills which gained him credit in the South Australian School of Arts and Crafts merit lists for 1934 and 1935.

Reginald Claude Sprigg, AO FTSE (1 March 1919 – 2 December 1994) was an Australian geologist and conservationist. At 17 he became the youngest Fellow of the Royal Society of South Australia. During 1946, in the Ediacara Hills, South Australia he discovered the Ediacara biota, an assemblage of some of the most ancient animal fossils known. He was involved with oceanographic research and petroleum exploration by various companies that he initiated. In 1968, he acquired a derelict pastoral lease, Arkaroola, and transformed it into a wildlife sanctuary and wilderness reserve.

Reginald Claude Sprigg was born 1 March 1919 on South Australia's Yorke Peninsula where his family were living in the small town of Stansbury. His parents were Claude Augustus Sprigg and Pearl Alice Irene née Germein, who had married on 17 September 1913 in Stansbury. Reg was their third and youngest child, a brother to D'Arcy Kingsley and Constance Vera (Connie).
