Sir John William Downer, KCMG, KC (6 July 1843 – 2 August 1915) was an Australian politician who served two terms as Premier of South Australia, from 1885 to 1887 and again from 1892 to 1893. He later entered federal politics and served as a Senator for South Australia from 1901 to 1903. He was the first of four Australian politicians from the Downer family dynasty. Early life Born in Adelaide, John Downer (the son of Henry Downer who came to South Australia in 1838 and Jane Downer ) was educated on a scholarship at St Peter's College, Adelaide,. On 23 March 1867 he was admitted to the bar, and soon won a reputation as being among Adelaide's most talented and eloquent lawyers. South Australian politician Downer became a Queen's Counsel in 1878, the same year in which he was elected to the House of Assembly for Barossa. He represented this constituency until 1901, leaving it only to enter federal politics. In the House of Assembly he soon made his mark and became Attorney-General in John Cox Bray's cabinet on 24 June 1881. He endeavoured to bring in several law reforms, and though his married women's property bill was not passed, he succeeded in carrying bills allowing accused persons to give evidence on oath, and amending the insolvency and marriage acts. The government was defeated in June 1884, but a year later, on 16 June 1885, Downer himself became Premier for the first time, as well as being Attorney-General once again. While Premier, Downer oversaw the construction of the first train line from Adelaide to Melbourne. He also made significant contributions to establishing irrigation settlements along the Murray River. Although this ministry lasted two years and passed a fair amount of legislation, it was often in difficulties, and in June 1886 had to be reconstructed. At the Colonial Conference held in London during 1887, Downer represented South Australia, but during his return journey to Australia his government was defeated. This ministry was responsible for a tariff imposing increased protective duties. Downer was not in office again for several years, but in October 1892 again became Premier, taking also the portfolio of Chief Secretary. In May 1893 he exchanged this for the position of Treasurer of South Australia, but was ousted at the 1893 election by liberal Protectionist Kingston with the support of the new Labor Party led by John McPherson.
