Edward Gough Whitlam (11 July 1916 – 21 October 2014) was the 21st prime minister of Australia, serving from December 1972 to November 1975. To date the longest-serving federal leader of the Australian Labor Party (ALP), he was notable for being the head of a reformist and socially progressive government that ended with his controversial dismissal by the then-governor-general of Australia, Sir John Kerr, at the climax of the 1975 constitutional crisis. Whitlam remains the only Australian prime minister to have been removed from office by a governor-general.

Whitlam was an air navigator in the Royal Australian Air Force for four years during World War II, and worked as a barrister following the war. He was first elected to the Australian House of Representatives in 1952, becoming a member of parliament (MP) for the division of Werriwa. Whitlam became deputy leader of the Labor Party in 1960, and in 1967, after the retirement of Arthur Calwell, was elected leader of the party and became the Leader of the Opposition. After narrowly losing the 1969 federal election to John Gorton, Whitlam led Labor to victory at the 1972 election, after 23 years of Coalition government.

In its first term, the Whitlam government introduced numerous socially progressive and reformist policies and initiatives, including the termination of military conscription and the end of Australian involvement in the Vietnam War, institution of universal health care and free university education, and the implementation of legal aid programmes. With the opposition-controlled Australian Senate delaying passage of bills, Whitlam called a snap double dissolution election in May 1974 in which he won a slightly reduced majority in the House of Representatives, and picked up three Senate seats to hold equal Senate numbers to the opposition. The Whitlam government then instituted the first and only joint sitting enabled under section 57 of the Australian constitution as part of the double dissolution process. His government's second term was dominated by a declining economy suffering from the 1973 oil crisis and the 1970s global recession, as well as a political scandal known as the Loans affair, which led to the removal of two government ministers. The opposition continued to obstruct Whitlam's agenda in the Senate.

In late 1975, the opposition senators refused to allow a vote on the government's appropriation bills, returning them to the House of Representatives with a demand that the government go to an election. Whitlam argued that his government, which held a clear majority in the House of Representatives, was being held to ransom by the Senate. The crisis ended in mid-November, when governor-general Sir John Kerr dismissed him from office and commissioned the opposition leader, Malcolm Fraser, as caretaker prime minister. Labor lost the subsequent election by a landslide. Whitlam stepped down as leader of the party after losing again at the 1977 election, and retired from parliament the following year. Upon the election of the Hawke government in 1983, he was appointed as Ambassador to UNESCO; he was later elected a member of the UNESCO Executive Board. He remained active into his nineties. The propriety and circumstances of his dismissal and the legacy of his government have been frequently debated in the decades since he left office. Whitlam is often ranked in the upper-tier of Australian prime ministers by political experts and academics, with political journalist Paul Kelly writing in 1994 that "there is no doubt that in three years his government was responsible for more reforms and innovations than any other government in Australian history".

Edward Gough Whitlam was born on 11 July 1916 at the family home 'Ngara', 46 Rowland Street, Kew, a suburb of Melbourne, the elder of two children (his sister, Freda, was born four years after him), to Martha (née Maddocks) and Fred Whitlam. His father was a federal public servant who later was Commonwealth Crown Solicitor, and Whitlam senior's involvement in human rights issues was a powerful influence on his son. Since his maternal grandfather was also named Edward, from early childhood he was called by his middle name, Gough, which had come from his paternal grandfather who had been named after the British soldier Field-Marshal Hugh Gough, 1st Viscount Gough.

In 1918, Fred Whitlam was promoted to deputy Crown solicitor and transferred to Sydney. The family lived first in the North Shore suburb of Mosman and then in Turramurra. At age six, Gough began his education at Chatswood Church of England Girls' School (early primary schooling at a girls' school was not unusual for small boys at the time). After a year there, he attended Mowbray House School and Knox Grammar School in the suburbs of Sydney.

Fred Whitlam was promoted again in 1927, this time to Assistant Crown Solicitor. The position was located in the new national capital of Canberra, and the Whitlam family moved there. As of 2008, Whitlam was the only prime minister to have spent his formative years in Canberra. At the time, conditions remained primitive in what was dubbed "the bush capital" and "the land of the blowflies". Gough attended the government Telopea Park School. In 1932, Whitlam's father transferred him to Canberra Grammar School where, at the Speech Day ceremony that year, he was awarded a prize by the Governor-General, Sir Isaac Isaacs.

Whitlam enrolled at St Paul's College at the University of Sydney at the age of 18. He earned his first wages by appearing, with several other "Paulines", in a cabaret scene in the film The Broken Melody – the students were chosen because St Paul's required formal wear at dinner, and they could therefore supply their own costumes. After receiving a Bachelor of Arts degree with second-class honours in classics, Whitlam remained at St Paul's to study law. He had originally contemplated an academic career, but his lacklustre marks made that unlikely. Dropping out of Greek classes, he professed himself unable to care for the "dry as dust" lectures of Enoch Powell.
