1898 Obituary 
THOMAS DAWSON RIDLEY, born at Acklington, Northumberland, on the 4th February, 1825, was a descendant of the old Northumberland family of Ridleys, of Willimoteswick on South Tyne.
He began his career in the office of Henry Welch, an early member of the Institution, who was at that time County Surveyor of Northumberland. He was then employed by the contractor who carried out, under Sir John Rennie, the earliest works at Warkworth Harbour, after which he had a year’s experience, in 1845, on the construction of the Whitehaven Junction Railway.
His next move was to Harlow Hill, where, as one of the contractors, he was engaged in 1846 and 1847 in the construction of the reservoirs at Welton for the Newcastle and Gateshead Water Co
Mr. Ridley was then occupied for four years in sundry engineering and building operations in the district around Newcastle. Among these was the erection of some of the earlier works established at Jarrow by Palmer Brothers, which works eventually became large and important as Palmer’s Shipbuilding and Iron Company.
In 1853 he went to West Hartlepool to act asengineer and manager to the contractor, William Hutchinson, in the construction of the Swainson Dock. On the completion of that dook Mr. Ridley was engaged for upwards of a year at Hexham in the construction of a portion of the Border Counties Railway.
The work included the erection of a bridge across the River Tyne, near Hexham, designed by John F. Tone. The site was awkward and the foundations of a difficult character, below the 11 feet of water being an unlimited deopft hg ravel and boulders. He next took a contract for the Waskerley Deviation of the Stockton and Darlington Railway, after which in 1859 he undertook the execution of the Hermitage contract, extending from Newcastleton to Riccarton on the Border Union Railway, under Mr. Tone. In the latter case, owing to heavy rainfall and the slippery nature of the clay out of the cutbings, considerable trouble and anxiety were caused in respect to the embankments, which would not stand at anything like the specified slopes.
In 1864 Mr. Ridley became engineer and manager for A. W. Ritson in the execution of contract No. 2 of the Thames Embankment, extending from the landing-pier at Waterloo Bridge to the eastern end of Temple Gardens, and 6 years later he read before the Institution a Paper descriptive of the cofferdams he had designed for excluding the wateri n the prosecution of that work.
For that Paper he was awarded a Telford medal and premium. After the completion of the Thames Embankment, Mr. Ridley undertook a contract for the extension of the dock at Middlesbrough, settling in 1869 at Redcar, where he resided for the remainder of his life. During that period he executed many railway and other contracts, including a section of the Whitby, Redcar and Middlesbrough Railway ; the extension of the Great Eastern line to Chingford; heavy works of piling and excavation required in the construction of the Great Eastern Railway Company’s shipping quay at Parkeston, Harwich; the North Eastern Company’s branch from Sherburn House to Durham ; an extension of the Union Dock, West Hartlepool; heavy piling, concrete and masonry for the construction of the new Dowlais Ironworks at Cardiff; filter ponds for the Cardiff Corporation, and large extensions of the Consett Ironworks in the county of Durham.
Mr. Ridley died at his residence, Willimoteswick, Coatham, near Redcar, on the 13th January, 1898. He was elected an Associate on the 4th March, 1856.
