Thomas Denman, 3rd Baron Denman, , was a British aristocrat and politician who served as the fifth Governor-General of Australia, in office from 1911 to 1914. Denman was born into the English nobility, inheriting his title at the age of 19 from a great-uncle. He attended the Royal Military College, Sandhurst, and served in the Second Boer War. Denman sat with the Liberal Party in the House of Lords, and was made a Lord-in-waiting in 1905 and Chief Whip in 1907. He was appointed to the governor-generalship at the age of 36, and remains the youngest person to have held the position. Denman and his young family were immensely popular with the general public, and he enjoyed friendly relations with Prime Minister Andrew Fisher, with whom he shared many similar political opinions. However, he suffered from ill health and returned to England after less than three years as governor-general. Denman never again held public office, but remained active in the House of Lords and briefly commanded a unit in the First World War.
Denman was born in London on 16 November 1874, the son of Richard Denman and the former Helen Mary McMicking. His father was the grandson of Thomas Denman, 1st Baron Denman, who was Lord Chief Justice from 1832 to 1850. Denman was the second of three children, and the oldest son. His younger brother, Sir Richard Denman, was also a Liberal Party politician. Denman's parents divorced in 1878. His father did not remarry, and died in 1883 when his son was eight. However, his mother remarried twice – in 1879 to James Walker, and then in 1888 to Henry Primrose. In 1894, aged 19, Denman succeeded his great-uncle as Baron Denman; he took his seat in the House of Lords on his 21st birthday. He intended a military career and was a graduate of the Royal Military College, Sandhurst. Denman began his career in the Royal Scots, where he was promoted to lieutenant on 4 March 1896, but resigned in May 1899 and was placed in the Reserve. Returning to active service following the outbreak of the Second Boer War, he was on 3 February 1900 commissioned as a lieutenant of the 11th Battalion, Imperial Yeomanry, and left Liverpool for South Africa on the SS Cymric in March 1900. He was promoted to captain in the battalion on 18 July 1900, and the following year was appointed a captain in the Middlesex Imperial Yeomanry, followed by a promotion to major on 30 April 1902.
The Denmans arrived in Melbourne on 31 July 1911. They found Andrew Fisher's Labor government firmly in control. As the most politically liberal Governor-General yet appointed, he got on well with the Labor ministers, and his modesty and generosity with his father-in-law's money made him popular with the public. In October 1912, the New South Wales Premier, James McGowen "evicted" him from Government House, Sydney. On 12 March 1913, he inaugurated the site of the future national capital and Lady Denman formally announced its name, Canberra. On 12 March 2013, his great-nephew, the 6th Baron Denman and his wife attended celebrations in Canberra commemorating the centenary of the naming of the city. But Denman found that he had less real political influence than any previous Governor-General. As Australia, along with the other dominions, achieved political maturity, its Prime Minister communicated directly with his British counterpart, cutting the Colonial Secretary and the Governor-General out of the loop. The appointment of an Australian High Commissioner in London further reduced the Governor-General's diplomatic role. In May 1913 the Labor government was unexpectedly defeated at a general election by Joseph Cook's Liberals. But Labor retained control of the Senate and was determined to frustrate Cook's government at every turn. By early 1914 it was clear that a constitutional crisis was developing. Denman was in poor healththat he was allergic to Australia's national flower, the wattle, did not helpand his marriage was suffering from his wife's unhappiness at being so far from home. He felt he lacked the strength to deal with the political situation, and in May 1914 he resigned. The Denman Glacier in eastern Antarctica was named after Denman by Sir Douglas Mawson. It had been discovered by the Australasian Antarctic Expedition of 1911–14.
Later years
With the outbreak of the Great War, Denman commanded a Yeomanry regiment from 1914 until 1915. He was appointed Honorary Colonel of the 2nd Cavalry Divisional Signals on 11 April 1923. He remained loyal to Asquith and the Liberals and so did not hold office again, leading a quiet life until his death in Hove, Sussex, 22 days after that of his wife. He was succeeded in the barony by his son, Thomas Denman, 4th Baron Denman.
