Joseph Cahill, Australian politician, 29th Premier of New South Wales (b. 1891)
John Joseph Cahill (21 January 1891 – 22 October 1959), also known as Joe Cahill or J. J. Cahill, was a long-serving New South Wales politician, railway worker, trade unionist and Labor Party Premier of New South Wales from 1952 to his death in 1959. Born the son of Irish migrants in Redfern, New South Wales, Cahill worked for the New South Wales Government Railways from the age of 16 before joining the Australian Labor Party. Being a prominent unionist organiser, including being dismissed for his role in the 1917 general strike, Cahill was eventually elected to the Parliament of New South Wales for St George in 1925.
After many years of backbench service, including a term outside of parliament, Cahill was eventually appointed Secretary for Public Works in 1941 and Minister for Local Government in the government of William McKell in 1944, where he led significant reforms of local government in the state, including establishing a Royal commission in 1945, and passing the landmark Local Government (Areas) Act of 1948. Promoted to Deputy Premier in 1949, Cahill became Premier of New South Wales from April 1952 to his death in October 1959. His term as premier is primarily remembered for his government's role in post-war infrastructure development, which included the commissioning of the Sydney Opera House and construction of the expressway which now bears his name.
