Dr Geoffrey Lewis

In 1965, IBM selected a 16-year old schoolboy, Geoffrey Lewis, to make the first public demonstration in Australia of the IBM System 360. Described in the newspapers as a genius, he was selected because of a sensational score of “150 out of 120” in a university test for mathematical aptitude. The 30 extra marks were awarded for exceptional problem-solving ability and in the next 10 years nobody else ever got more than 75!
