Donald MacKintosh was born at Murlaggan, Lochaber, Scotland on 16th May 1840, son of
James MacKintosh, Murlaggan and his wife Mary MacArthur, Achavaddy. He emigrated to Warwick, Queensland, Australia in 1863 where he met his wife, Catherine Cowhey.
He started the first cheese factory in the Pittsworth district, the Glencairn Cheese Factory, and won many prizes for both cheese and butter. At the
1897 Jubilee Exhibition in Brisbane, his butter and cheese both secured gold medals.
Mr. Mackintosh was the first chairman of the Greenmount State School, and was the prime mover in the establishment of many schools at centres on the Downs, notably Greenmount and Harelmar.
He was a well-known figure in executive capacities and was among the first members to be appointed to some Government positions in local shires. His appointment as a Justice of the Peace was one of the earliest made in the State.
The Hibernian Society at Pittsworth too, can claim to have the name of Mr. Mackintosh as an honoured one among its members. Indeed he established the Hibernian Society.
However, it was as a member of the Legislative Assembly that the name of the old pioneer became a familiar one throughout the country.
Mr. Mackintosh entered Parliament in 1899, elected for Cambooya. He held his seat until 1915 when the Cambooya electorate became the PIttsworth electorate.
He died aged in 1832 aged 91, a father of 13 children and 29 grandchildren.
