John Curtin (8 January 1885 – 5 July 1945) was an Australian politician who served as the 14th prime minister of Australia from 1941 until his death in 1945. He held office as the leader of the Australian Labor Party (ALP), having been most notable for leading the country through the majority of World War II, including all but the last few weeks of the war in the Pacific. Curtin's leadership skills and personal character were acclaimed by his political contemporaries, and he is frequently ranked as one of Australia's greatest prime ministers and political leaders.
Curtin left school at the age of 13 and became involved in the labour movement in Melbourne. He joined the Labor Party at a young age and was also involved with the Victorian Socialist Party. He became state secretary of the Timberworkers' Union in 1911 and federal president in 1914. Curtin was a leader of the "No" campaign during the 1916 referendum on overseas conscription, and was briefly jailed for refusing to attend a compulsory medical examination. He moved to Perth the following year to become the editor of the Westralian Worker, and later was state president of the Australian Journalists' Association.
