John Thomas Gannon (18305 August 1887) was a politician and solicitor in New South Wales, Australia.
He was born in Sydney in around 1830, the second child of convict James Gannon and his wife Mary Phelps. A younger brother Michael would later be a member of the Queensland Legislative Assembly.[1] He attended state schools before becoming an articled clerk to Bob Nichols. On 12 July 1855 he married Harriette Mary Jones, with whom he had four children. He was admitted as a solicitor in 1857.[2] before moving to Goulburn from 1859.
He served as Mayor of Goulburn from 1872 to 1873.[3] [4] He was elected to the New South Wales Legislative Assembly for Argyle at the by-election in 1881, serving until he resigned in March 1885.
Gannon died at Parramatta in 1887, aged around 56.[5] [6] [7]
His eldest son, Henry Shuttleworth followed his father, practicing as a solicitor, and was Mayor of Goulburn in 1888 and 1889, but was unsuccessful in standing for parliament at the 1890 by-election for Goulburn,[8] and the 1894 election for Argyle.[9] In 1897 he ostensibly went on holiday to Fiji, but in fact fled to the United States after misappropriating nearly £15,000 of client's money.[10] [11] [12]
