David Blair (4 June 1820 – 19 February 1899) was an Irish Australian politician, journalist and encyclopedist.

David Blair was born in County Monaghan, Ireland to parents of Scottish descent. He studied at the Hibernian Military School, Dublin. He left in 1835, aged 15 years and worked in an uncle's business but did not enjoy it.^[1]

In 1840 he joined the Ordnance Survey of Ireland as a calculator stationed in Limerick and then Cork. He transferred to Southampton in 1841 and for almost nine years he worked on the triangulation of England and the survey of London.^[1]

Blair was so unhappy in his work that he considered joining the military.^[1] He supported the revolutionary Chartists as a lecturer in Southampton, in reading and in church activities. ^{[citation needed]}

He later studied for the ministry in Ireland^[1] and came to Australia in 1850 at the suggestion of John Dunmore Lang, the intention being that he should go into the back country as a missionary. He took up journalism in Sydney, where he was associated with Henry Parkes on the Empire newspaper. Blair went to Victoria in 1852 and had a long and varied career as a journalist, including a long stint as leader writer for The Age^[2] and as a contributor to Victorian Review.^[3]

Blair was elected a member of the legislative assembly of Victoria in 1856 and again in 1868, but did not make any special mark in politics. In 1876 he edited the Speeches of Henry Parkes, and in 1878 or 1879 he published the important The History of Australasia--to the Establishment of Self-Government, based largely on the works of his predecessors, and Cyclopedia of Australasia (1881). He also wrote The First Imaginary Voyage to Australia (1882). He died at Melbourne on 19 February 1899, aged 78.

Blair's wife Annie McPherson was the sister of James Macpherson Grant MLA.^[4] Their daughter Florence Baverstock has been noted as a fine writer,^[5] having on occasion contributed articles for her father when he was indisposed. In September 1896 she replaced the dangerously ill Ina Wildman ("Sappho Smith") as editor of The Bulletin's Women's pages.^[6]
