David Ngunaitponi (Unaipon) (28 September 1872 – 7 February 1967)
Today, I pay homage to a great Australian inventor.
What a fascinating piece of history. Sadly many great ideas fail to make it past the provisional patent application stage. David's story is not uncommon, but that does not lessen the poignancy.
I will leave you to read the link above to the Wikipedia article.
A truly great man. Pause for a moment to consider the strength of character that it must have taken to succeed as an aboriginal in those days.
I'm sorry I was too late for him to knock on my door. Rest in glory, David.
