WILLIAM ARMSTRONG was born at Wingate, Co. Durham, in 1846. He was educated at Rossall School and afterwards at the University of Edinburgh.
His apprenticeship as a mining engineer was served with the late Mr. John Daglish at the Marquess of Londonderry's Collieries, and subsequently he succeeded his father as agent at Wingate Colliery.
This position he resigned in 1909 in order that he might devote his whole services to the firm of William Armstrong and Sons, consulting mining engineers of Newcastle-on-Tyne.
He was a Justice of the Peace for the County of Durham, and was for many years consulting engineer to the Pemberton Collieries in Lancashire.
He became a Member of this Institution in 1876; he was also a Member of the Institution of Civil Engineers and of the North of England Institute of Mining and Mechanical Engineers, of which latter Institute he was President for the two years 1898-1900.
His death took place at Gosforth on 30th March 1918, in his seventy-second year.
