David Unaipon – the inventor
David Unaipon was born in 1872, at Point McLeay on a South Australian Christian Mission, and trained to be an Aboriginal Christian Preacher. Soon he was acting as a spokesman for the Indigenous community and by the early 1900’s was famous. He won nationwide respect and his articles about Aboriginal Myths and Legends were published in newspapers and Christian magazines, a first for an Aborigine. In 1909 Unaipon invented an improved mechanical hand piece for shearing sheep by changing the motion of the blades from circular to straight. While he obtained a patent for his new shears he was never properly protected and it was others who gained financially from his invention. That didn’t stop Unaipon. Interested in aerodynamics he conducted experiments involving the flight of boomerangs and then predicted the invention of Helicopter flight. He was called Australia’s Leonardo and came up with ideas for a centrifugal motor and a multi-radial wheel idea.
