Sir Ian Clunies-Ross

(1899–1959)
Ian Clunies-Ross was born in Bathurst, New South Wales. He was a scientist who worked with animals.

He was a Professor of Veterinary Science at Sydney University and was the first chairman of the CSIRO (Commonwealth Scientific and Industrial Research Organisation). This organisation was set up by the Commonwealth government. It has several sections that carry out experiments to help farmers find better ways to grow things and look after the environment. Clunies-Ross worked to improve the sheep and wool industry, conducting experiments to grow better wool and to help farmers protect the sheep from disease.  

Clunies-Ross has had an animal research laboratory near Sydney named after him and his face appears on the $50 note. He was also knighted (made a 'Sir') by Queen Elizabeth II.
