1909. Point McLeay Mission, South Australia.
David Unaipon was a Ngarrindjeri inventor, writer, preacher, and self taught mechanic who studied machines from inside a mission settlement. He designed an improved handpiece for sheep shearing, a small mechanical answer to one of Australia's central rural industries. The idea was taken into use, but the money and credit did not follow him.
He was born on September 28, 1872, at Point McLeay Mission on the lower Murray in South Australia. His father, James Ngunaitponi, was an evangelist. His mother, Nymbulda, was a Yaraldi speaker. David was the fourth of nine children and entered the mission school at seven.
The mission gave lessons, rules, scripture, and limits.
At thirteen, he left Point McLeay to work as a servant for C B Young, who encouraged his reading in philosophy, science, and music. Unaipon later returned to the mission, played the organ, learned bootmaking, and read scientific works whenever he could get them. He became absorbed by motion, force, and the dream of machines that could keep moving.
The books were scarce. The hunger was not.
By the late 1890s, he had gone to Adelaide looking for work, but race blocked him from trades that matched his skill. He worked for a bootmaker, then returned to Point McLeay as a bookkeeper in the mission store. The bench, the tool, and the drawing page stayed with him.
Sheep shearing gave him a precise problem.
Mechanical handpieces could seize under the stress of work. Unaipon studied the motion of the tool and designed a modified handpiece that converted rotary motion into a straighter cutting movement. The aim was practical: reduce strain, improve action, and make the machine less likely to jam while cutting wool.
It was not an abstract invention. It belonged to the shed.
In 1909, he obtained protection for the shearing idea with help from Herbert Basedow, a South Australian doctor and former official connected to Aboriginal affairs. Later accounts describe it as a provisional patent rather than a fully secured patent. AIATSIS records that Unaipon could not afford to get the invention fully protected. The design was later adopted.
He received no financial reward.
A 1910 newspaper report acknowledged him as the inventor, but that was not enough to hold the work to his name. He went on to make patent applications for other inventions, including a centrifugal motor, a multi radial wheel, and a mechanical propulsion device. The Australian Dictionary of Biography records that those later patents lapsed.
He kept inventing in a country built to deny Aboriginal ownership.
Unaipon also became a public speaker and an early Aboriginal author. In the 1920s, he collected and wrote versions of Aboriginal stories. His manuscript was later published in 1930 under the name of William Ramsay Smith, without acknowledgment. The book did not appear under Unaipon's name until decades after his death.
The theft was not limited to metal.
He travelled for the Aborigines' Friends' Association, preached, lectured, and spoke before inquiries on Aboriginal affairs. He was often refused accommodation because of his race. In old age, he returned to Point McLeay and continued working on inventions. He died at Tailem Bend Hospital on February 7, 1967.
His face later appeared on the Australian fifty dollar note.
Unaipon's shearing handpiece became part of the record of Australian mechanical invention, and his writing became part of the foundation of Aboriginal literature in English.
He drew machines and stories into existence, and both were taken from him before they were returned.
