David Unaipon (1872- 1967)

David Unaipon is the man who appears on the 50 dollar note along with his drawings of his inventions in the foreground. His most successful invention was a sheering machine. He is the uncle of Stevie Goldsmith from the post below. Stevie asked if we knew who he was and if not why not. I will be honest I did not know who David Unaipon was, these are things we should be taught in school, it isnt enough to be on a 50 dollar note.
