Born in Renton, Dunbartonshire, Duncan McLaren was the youngest of ten children of John McLaren and Catherine McLellan. Apart from two years of schooling, he was self-taught. After school, he was apprenticed to a merchant in Dunbar. In 1824, he set up his own business as a draper in Edinburgh, growing the store into one if Britain's first department stores.^[1] In the 1830s, he headed the Scottish Central Board of Dissenters, established in 1834.^[2]

McLaren became a member of the town council in 1833. He became treasurer in 1837 and found that the royal burgh's finances were in ruin and that the Scottish capital was bankrupt. His work extricated Edinburgh from financial ruin. In 1835, he pioneered free education for all classes and started a building programme of thirteen schools.

He was elected Lord Provost of Edinburgh in 1851. McLaren was a Liberal and supported the anti–Corn Law campaign of John Bright, the opening of the Meadows to the public, and the establishment of the Industrial Museum (now the National Museum of Scotland). McLaren was also a governor of the Heriot Free School trust.^[3]

McLaren campaigned against the decision of the trustees of William Fettes to use his bequest to found a 'public school' on the English model, believing that to be a misuse of funds intended for the education of orphans and the needy. He sought unsuccessfully to have the Fettes project remodelled to create free schools on similar lines to those supported by the Heriot Trust.^[4]

In 1865 he was elected one of Edinburgh's two Members of Parliament, a position he held until he retired 16 years later. At Westminster he proved a conscientious and intelligent representative, and acquired a position of so much authority on questions related to Scotland that he was called "Member for Scotland".^[3] He was then living in Newington House.^[5]

Duncan McLaren was married three times – the third being Priscilla Bright (sister of John Bright and Margaret Bright Lucas), whom he married in 1848, and they lived together in Newington House, Edinburgh, from 1852 until his death in 1886. He is buried (together with most of his family) in St Cuthbert's Churchyard in the heart of Edinburgh. His huge monument lies against the east wall of the first south extension to the graveyard, immediately below Edinburgh Castle.

McLaren married three times.

Firstly, in 1829, he married Grant Aitken^[3] (1805–1833). Following her death he married Christina Gordon Renton (1813–1841). Finally, in 1848, he married Priscilla Bright (1815–1906), who outlived him by twenty years. All three wives are buried with him.

He was the father of John McLaren (son of his first wife), Agnes McLaren, Catherine McLaren (mother of F. S. Oliver) (with his second wife Christina Renton), and then Charles McLaren, Helen Priscilla McLaren and Walter Stowe Bright McLaren (with his third wife Priscilla Bright McLaren).

A full-length portrait of McLaren by George Reid RSA hangs in the Old Council Chamber (now called the Diamond Jubilee Room) within Edinburgh City Chambers.
