Jonathan Duncan was born in 1799 in Bombay, where his father – also Jonathan Duncan – was governor. He died in Notting Hill, London on 20 October 1865. Initially Duncan was educated by a private tutor and then on 24 January 1817 he entered Trinity College, Cambridge. He was awarded a BA in 1821. Financially, Duncan was very secure and therefore he did not need to find employment. Instead, he became involved in literature and politics and published a number of pamphlets and books on a variety of topics. He was particularly interested in currency reform and economics.
