William Leslie

• Illustration — The Bridge of Dee, Aberdeen He was born at New Deer in Aberdeenshire into a Congregationalist family. By 1828 he was an established architect in Aberdeen living at Park Cottage on Broadford. He also started operating as a building contractor, and in this capacity was one of the city's largest employers, employing over 150 men. In 1836 he was appointed agent for the repair and maintenance of the Duke of Sutherland's estates undertaking, design, engineering and construction tasks. In 1838 he formed a new company: McDonald & Leslie, based in Dornoch, having merged with granite sculptors Alexander NcDonald & Co. His work began to gravitate mainly to Aberdeen and in 1850 he opened an office at 8 Golden Square. In 1853 he dissolved the partnership with McDonald and began to concentrate on Aberdeen affairs, becoming a town councillor around this time. In 1866 he privately financed the building of Woodside Congregational Church (now Church of Scotland). From 1868 his business address was 123 Union Street, Aberdeen. He was elected Lord Provost of Aberdeen in 1869 being succeeded in 1874 by George Jamieson. Around 1872 he remodelled Nethermuir House in New Deer as his home. The house bears a lintel of 1595 but was largely built around 1803. It is now ruinous but is a listed building. He died at his Aberdeen townhouse, 28 Albyn Place, on 18 February 1879.
