He was the son of Thomas Dundas and Bethia Baillie. He made his first fortune as Commissary General: supplying goods to the
British Army during the
Jacobite rising of 1745 and the
Seven Years' War. Dundas subsequently branched out into banking, property (he developed
Grangemouth in 1777) and was a major backer of the
Forth and Clyde Canal which happened to run through his estate, centred on Kerse House, near
Falkirk. He left his son an inheritance worth £900,000. Sir Lawrence was also a man of taste, elected a member of the
Society of Dilettanti in 1750. He bought the
Aske Estate, near
Richmond in North Yorkshire in 1763 from
Lord Holderness for £45,000 and proceeded to enlarge and remodel it in
Palladian taste by the premier Yorkshire architect,
John Carr, who also designed new stables. Dundas also acquired ownership over two
slave plantations in the
British West Indies, one in
Dominica and one in
Grenada. In 1768, he acquired a tavern "Peace and Plenty" on the land destined to become
Edinburgh's New Town. This was shown on James Craig's plan as a potential site for a church, but Dundas's wealth and ownership of the site allowed him to design his own mansion here, somewhat off the grid of the New Town. This house, now
Dundas House in St. Andrew Square, was designed by
Sir William Chambers, became the headquarters of the
Royal Bank of Scotland in 1825. The facade and later 1857 ceiling feature on the current designs of the banknotes issued by the Royal Bank. He purchased
Giacomo Leoni's grand house near London,
Moor Park, for which he ordered a set of
Gobelins tapestry hangings with medallions by
François Boucher and a long suite of seat furniture to match, for which
Robert Adam provided designs: they are among the earliest English
neoclassical furniture. Other new furnishings, for Aske and for Sir Lawrence's magnificently appointed London house at 19 Arlington Street, were supplied by
Thomas Chippendale (1763–66), and Chippendale's rivals, the royal cabinet-makers
William Vile and
John Cobb, and Samuel Norman (Gilbert). A pair of marquetry commodes in the French taste by a French cabinet-maker working in London, Pierre Langlois, is at Aske.
Capability Brown worked on the park at Aske and provided a design for a bridge. In the 1770s, Sir Lawrence turned to Robert Adam for further remodelling and designs for furnishings. The Aske estate included the
pocket borough of
Richmond, so Sir Lawrence was, therefore, able to appoint the Member of Parliament. Sir Lawrence married Margaret Bruce, and they had one son,
Thomas Dundas.
James Boswell described Dundas as "a comely jovial Scotch gentleman of good address but not bright parts ... I liked him much". Dundas was a great collector of art. Long after his death, Messrs Greenwood sold 116 of his paintings on 29–31 May 1794 from their room in Leicester Square. They included works by
Cuyp,
Murillo,
Raphael,
Rubens and
Teniers. Some of the Murillo's and perhaps other works would have been bought on commission by Dundas's friend
John Blackwood. Sir Lawrence died in 1781 and is buried in the Dundas Mausoleum at
Falkirk Old Parish Church where his wife Margaret and son Thomas eventually joined him. == Notes ==
