WILLIAM LAWRIE TURNBULL was born in Glasgow on 3rd July 1870.
He was educated at the High School and Allan Glen's School, Glasgow, and attended engineering classes at the University of Glasgow. His apprenticeship of five years was served partly in the works of Messrs. Clarkson Brothers and partly at the Canal Basin Foundry, Port Dundas, Glasgow, after which he was engaged in the drawing office of his father for three years. In this connection he designed and superintended the erection of various water-power Plants in Great Britain.
He then went to America for a short time to study the water-turbine business, and after his return he joined his father as partner, the firm becoming John Turnbull, Jun. and Sons, consulting engineers. Amongst some of the later work with which he was connected may be mentioned the installation of several large "Hercules" turbine sets. His death took place at his residence at Bridge-of-Weir, Scotland, on 20th February 1911, in his forty-first year. He became a Member of this Institution in 1904; he was also a Member of the Institution of Engineers and Shipbuilders in Scotland.
