David Unaipon

David Unaipon was born on September 28, 1872, at the Point McLeay Mission on the shore of Lake Alexandrina in South Australia, a settlement known to its Ngarrindjeri residents as Raukkan ^[1]. He was the fourth of nine children of James Ngunaitponi and his wife Nymbulda, both Yaraldi speakers of the Ngarrindjeri nation. His father had become the first Aboriginal convert of the mission's founder, the Congregationalist preacher George Taplin, and worked there as an evangelist, so David grew up in a household where Christian scripture and Ngarrindjeri tradition sat side by side ^[1].

The boy entered the mission school at age seven and quickly drew attention for his memory and curiosity. At thirteen he left Raukkan for Adelaide to work as a servant in the household of C. B. Young, a prominent supporter of the mission, who encouraged his reading in science, literature, philosophy, and music ^[1]. Those Adelaide years gave Unaipon access to books and instruments that the mission could not supply, and he taught himself widely, developing particular passions for mechanics and the organ.

He returned to Point McLeay in his late teens and took an apprenticeship with a bootmaker while serving as the mission organist. Later he worked as a bookkeeper in a Port Adelaide store before returning again to the mission, where steady employment for an educated Aboriginal man remained scarce ^[1]. The pattern of movement between Raukkan and the wider colony would shape the rest of his life.

From the 1890s Unaipon threw himself into the problem that would occupy him for decades: perpetual motion. He accepted that the goal was considered impossible, yet he treated the search as a spur to serious study of physics and mechanics, and he returned to the question throughout his life ^[1]. The discipline of that pursuit fed a stream of practical experiments in his workshop.

Around the turn of the century he began working for the Aborigines' Friends' Association, the philanthropic body that helped administer Point McLeay. As a deputationer he travelled through South Australia and beyond, preaching in churches of many denominations, lecturing on Aboriginal culture and legends, and collecting subscriptions for the mission ^[1]. The role made him one of the most widely travelled Aboriginal men of his era, and audiences in country towns and city halls came to know his precise diction and command of scripture.

His public speaking carried a consistent argument: that Aboriginal people possessed full intellectual equality with other Australians and needed only education and opportunity to demonstrate it. Unaipon presented himself as living proof, and newspapers of the period reported his lectures with a mixture of admiration and surprise that says much about the prejudices he faced ^[4]. He was often described in the press of his day as a remarkable exception, a framing he used to challenge the assumptions behind it.

Any account of David Unaipon achievements has to begin with the shearing shed. In 1909 he took out a provisional patent for an improved mechanical handpiece for sheep shearing, a design that converted rotary motion into the straight line movement of the cutting blades ^[1][4]. The principle he introduced was later reflected in the modern handpieces used across the Australian wool industry, although Unaipon himself never earned money from it because he lacked the funds to carry the application through to a full patent.

Between 1909 and 1944 he lodged provisional applications for nineteen inventions in all, covering devices as varied as a centrifugal motor, a multi radial wheel, and a sheep shearing handpiece of improved design ^[4]. None proceeded to a sealed patent, a fact that reflected his poverty rather than the quality of his ideas. Drawing on his study of the boomerang's flight, he also wrote about the possibility of aircraft that could rise vertically, anticipating the helicopter years before such machines flew ^[4].

His reputation as a thinker earned him the newspaper label of Australia's Leonardo, a comparison repeated often in later commemorations ^[5]. Unaipon took the scientific work seriously to the end of his life, still sketching designs and pursuing his perpetual motion studies into his ninth decade ^[1].

Unaipon's literary work broke new ground for Aboriginal Australians. During the 1920s he began writing down Ngarrindjeri and other Aboriginal stories in English, and in 1929 the small booklet Native Legends appeared under his name, making him the first Aboriginal author to publish a book in English ^[2][4]. He composed his prose in a deliberately formal register modelled on Milton and Bunyan, authors he had absorbed since boyhood.

The larger manuscript he prepared for the publisher Angus and Robertson met a harsher fate. The material was sold to the Adelaide coroner and amateur anthropologist William Ramsay Smith, who published it in 1930 as Myths and Legends of the Australian Aboriginals without acknowledging Unaipon at all ^[2]. Only in 2001, when the scholars Stephen Muecke and Adam Shoemaker restored the text and published it as Legendary Tales of the Australian Aborigines under Unaipon's own name, was the authorship publicly corrected ^[2].

He was also a persistent political voice. In 1926 he supported proposals for a separate territory for Aboriginal people in central and northern Australia, and in 1928 and 1929 he gave evidence to the Bleakley inquiry into Aboriginal welfare ^[1]. He pressed governments for better education, for Aboriginal involvement in the administration of Aboriginal affairs, and for the replacement of state control with Commonwealth responsibility, arguments that anticipated changes which arrived only after his death ^[4].

In January 1902 Unaipon married Katherine Carter, born Sumner, a Tangani woman of the Coorong region, at Point McLeay ^[1]. The marriage produced a son, but Unaipon's constant travelling for the Aborigines' Friends' Association kept him away from home for long stretches, and the couple spent much of their later married life apart.

Faith anchored his daily routine. Raised in his father's Congregationalist tradition, he preached to congregations of many denominations and read scripture throughout his life, seeing no conflict between Christian belief and pride in Ngarrindjeri knowledge ^[1]. Music remained a private pleasure; he had served as the mission organist in his youth and kept his love of the instrument.

Despite his fame, money was always short. He lived frugally, funding his patent applications and travel from lecture fees and the modest support of the Association, and he experienced the same discriminatory restrictions on movement and employment that governed the lives of other Aboriginal South Australians of his generation ^[4].

Unaipon kept working long past the age when most men retired. He continued his deputation journeys for the Aborigines' Friends' Association until the late 1950s, by which time he had spent roughly half a century travelling on the organisation's behalf ^[1]. In 1953 his contribution to Australian life was recognised with the Coronation Medal issued for the accession of Queen Elizabeth II ^[1].

In old age he returned to live at Raukkan, the community of his birth, where he carried on with his experiments and his reading. Visitors found him still absorbed in the mechanics of perpetual motion and still convinced that patient study would reward him ^[1].

David Unaipon died at Tailem Bend Hospital in South Australia on February 7, 1967, aged 94, and was buried in the Raukkan cemetery ^[1]. His death came in the same year that Australians voted overwhelmingly in the referendum to count Aboriginal people in the census and allow the Commonwealth to legislate for them, a change consistent with arguments he had made for decades ^[4].

Recognition grew steadily after his death. Since 1995 Unaipon's portrait has appeared on the Australian fifty dollar note, alongside images of the mission church at Raukkan, his shearing handpiece drawings, and text from his writings, placing his face in the hands of millions of Australians every day ^[3][4]. Few of the everyday David Unaipon facts are better known than this one, yet many who carry the note still cannot name the man on it.

Literature honours him as well. The David Unaipon Award, established in 1988, is presented annually to the best unpublished manuscript by an Aboriginal or Torres Strait Islander writer, and it has launched the careers of several significant Indigenous authors ^[4]. The University of South Australia named the David Unaipon College of Indigenous Education and Research after him, and his restored Legendary Tales is now studied as a founding work of Aboriginal literature in English ^[2].

For readers of any David Unaipon biography, the through line is clear. A man born on a mission with no formal schooling beyond age thirteen became an inventor, the first published Aboriginal author, a preacher heard across two states, and an advocate whose proposals reached royal commissions ^[1][4]. His life demonstrated exactly what he spent it arguing: that ability recognises no boundary of race.
