Collab Echoes: Echoes of the Murray River

David Unaipon, Ngarrindjeri man, was a preacher, public speaker, educator, inventor and the first Aboriginal writer to publish in English.

He was born at Raukkan in the Coorong in 1872, son of Yaraldi parents from the lower murray.

As an inventor he took out nine patent applications between 1909 and 1944. His particular interest lay in converting rotary to linear motion.

You can view the 1909 Patent specification for Mechanically driven Sheep shears at the Treasure Wall at the State Library of South Australia.
