Turnbull Robt. I.A. (10:00 pound Sterling)
Robert Turnbull (1841-1905) was Thomspn's partner from 1872. He continued the Architectural business, often adapting Thomson designs, after Thomson's death in 1875, initially in partnership with David Thomson (no relation). Robert Turnbull was the eldest son of William Turnbull, born in Mossburnford, Roxburgh, in 1840. He was educated at Glendouglas School and at 11 was apprenticed to his father; he subsequently studied at the Watt institute, Edinburgh and Andersonian College Glasgow. He was twice married, in 1863 to Jane Weir Watson, youngest daughter of James Turnbull, of Cavers, and in 1877 to Fanny Patullo, third daughter of Francis Watson, of Blackhall. A son and a daughter survived him.
He was taken into partnership by alexander Thomson after George Thomson departed for Cameroon as a missionary. After 1870, the partnership was known as A. Thomson and Turnbull. After Thomson's death in 1875, Turnbull took David Thomson into partnership as D. Thomson and Turnbull.
In 1880, D. Thomson and Turnbull I.A. were listed as designers of a new public hall in Thornliebank, and in 1886 as winners of the competition to design Old Kilpatrick Board School, Clydebank.
Turnbull is suggested as designer ofHarwarden Terrace, Partickhill, and may have designed 74 Partickhill Road. He was a member of the Institute of Architects for 28yrs, a member of and contributor to the Royal Philosophical Society. For 14years he was variously a member of the Parochial Board of Cadder, a member of the Parish local authority, Convener of Cadder district Committee under Roads and Bridges Act, County Councillor of the Lower Ward district of Lanarkshire 1890-5, member of the Valuation Committee, Highways Committee, Court House Management for the County, Public Health Board and a Commissioner of supply for the County of Lanark. He appears to have been responsible for a number of Villas and terraces in Thomsonesque style in Lenzie, where he died at his home, "Ruberslaw".
