Andrew Inglis Clark

Andrew Inglis Clark (24 February 1848 – 14 November 1907) was an Australian founding father and co-author of the Australian Constitution; he was also an engineer, barrister, politician, electoral reformer and jurist. He initially qualified as an engineer, but he re-trained as a barrister to effectively fight for social causes which deeply concerned him. After a long political career, mostly spent as Attorney-General and briefly as Opposition Leader, he was appointed a Senior Justice of the Supreme Court of Tasmania. Despite being acknowledged as the leading expert on the Australian Constitution, he was never appointed to the High Court of Australia. -Wikipedia
