Laurie John Ferguson (4 September 1924 – 17 September 2002) was an Australian politician and member of the New South Wales Legislative Assembly for the Australian Labor Party (New South Wales Branch). He served in Neville Wran's state government as the Deputy Premier of New South Wales from 1976 to 1984.
Born in the inner Sydney suburb of Zetland, Ferguson was educated at Granville Convent and Marist Brothers College, Parramatta, both Catholic schools.[1]
After leaving school he was variously a farmhand, textile worker, builder's labourer and bricklayer and was an organiser for the Building Workers' Industrial Union. From 1942 to 1946 he served in the Second Australian Imperial Force.
Following his demobilisation, he became active in municipal, and then state, politics. He was an alderman on Parramatta Council from 1954 to 1959, and Deputy Mayor in 1959. He married Mary Ellen Bett; the couple had three sons (Laurie, Martin and Andrew) and two daughters.[2]
Ferguson was the member for Merrylands from March 1959 to 1962 and 1968 to 5 March 1984. From 1962 to 1968, he was member for Fairfield. A member of the Labor Party's left wing, he was best known as Deputy Premier and Minister for Public Works and Minister for Ports, from May 1976 until February 1984, in the cabinet headed by Neville Wran. He was also Minister for Housing from May 1976 to February 1977.[2]
Ferguson died in Sydney on, from mesothelioma according to his son Andrew.[3]
