Although this was first broadcast in 2007 I just discovered it thanks to a recent replay. I love Dr Karl's podcasts on ABC Triple J & BBC 5 Live and saw his awesome presentation at TAMOZ 2010 (right).
This conversation is remarkable for his parents story, as much as his own. I’m glad it was repeated, it’s well worth your time:
Dr Karl is famous for his boundless enthusiasm for all things science.
But the details of his own incredible life are less familiar - before he became a medical doctor, Dr Karl worked as a mechanic, a roadie (for people like Bo Diddley and Chuck Berry), a steel worker and a filmmaker.
In 1995 he took up the position of the Julius Sumner Miller Fellow at Sydney University, spreading the good word about science and its benefits.
Among his many accolades, one of his favourites is being named Australia's Father of the Year in 2003.
