Life and work

After spending five years in the army during the Napoleonic Wars, Austin turned to law, and spent seven unhappy years practicing at the Chancery bar. In 1819, he married Sarah Taylor and became neighbours and close friends with Jeremy Bentham, James Mill, and John Stuart Mill. Mainly through Bentham's influence, Austin was appointed Professor of Jurisprudence at the newly-founded University College London in July 1827. However, Austin's lectures were not well-attended and he resigned his university post in 1834.
