1 Kirkaldy, David
[br]b. 4 April 1820 Mayfield, Dundee, Scotlandd. 25 January 1897 London, England[br]Scottish engineer and pioneer in materials testing.[br]The son of a merchant of Dundee, Kirkaldy was educated there, then at Merchiston Castle School, Edinburgh, and at Edinburgh University. For a while he worked in his father's office, but with a preference for engineering, in 1843 he commenced an apprenticeship at the Glasgow works of Robert Napier. After four years in the shops he was transferred to the drawing office and in a very few years rose to become Chief. Here Kirkaldy demonstrated a remarkable talent both for the meticulous recording of observations and data and for technical drawing. His work also had an aesthetic appeal and four of his drawings of Napier steamships were shown at the Paris Exhibition of 1855, earning both Napier and Kirkaldy a medal. His "as fitted" set of drawings of the Cunard Liner Persia, which had been built in 1855, is now in the possession of the National Maritime Museum at Greenwich, London; it is regarded as one of the finest examples of its kind in the world, and has even been exhibited at the Royal Academy in London.With the impending order for the Royal Naval Ironclad Black Prince (sister ship to HMS Warrior, now preserved at Portsmouth) and for some high-pressure marine boilers and engines, there was need for a close scientific analysis of the physical properties of iron and steel. Kirkaldy, now designated Chief Draughtsman and Calculator, was placed in charge of this work, which included comparisons of puddled steel and wrought iron, using a simple lever-arm testing machine. The tests lasted some three years and resulted in Kirkaldy's most important publication, Experiments on Wrought Iron and Steel (1862, London), which gained him wide recognition for his careful and thorough work. Napier's did not encourage him to continue testing; but realizing the growing importance of materials testing, Kirkaldy resigned from the shipyard in 1861. For the next two and a half years Kirkaldy worked on the design of a massive testing machine that was manufactured in Leeds and installed in premises in London, at The Grove, Southwark.The works was open for trade in January 1866 and engineers soon began to bring him specimens for testing on the great machine: Joseph Cubitt (son of William Cubitt) brought him samples of the materials for the new Blackfriars Bridge, which was then under construction. Soon The Grove became too cramped and Kirkaldy moved to 99 Southwark Street, reopening in January 1874. In the years that followed, Kirkaldy gained a worldwide reputation for rigorous and meticulous testing and recording of results, coupled with the highest integrity. He numbered the most distinguished engineers of the time among his clients.After Kirkaldy's death, his son William George, whom he had taken into partnership, carried on the business. When the son died in 1914, his widow took charge until her death in 1938, when the grandson David became proprietor. He sold out to Treharne \& Davies, chemical consultants, in 1965, but the works finally closed in 1974. The future of the premises and the testing machine at first seemed threatened, but that has now been secured and the machine is once more in working order. Over almost one hundred years of trading in South London, the company was involved in many famous enquiries, including the analysis of the iron from the ill-fated Tay Bridge (see Bouch, Sir Thomas).[br]Principal Honours and DistinctionsInstitution of Engineers and Shipbuilders in Scotland Gold Medal 1864.Bibliography1862, Results of an Experimental Inquiry into the Tensile Strength and Other Properties of Wrought Iron and Steel (originally presented as a paper to the 1860–1 session of the Scottish Shipbuilders' Association).Further ReadingD.P.Smith, 1981, "David Kirkaldy (1820–97) and engineering materials testing", Transactions of the Newcomen Society 52:49–65 (a clear and well-documented account).LRD / FMW -

SUBJECT AREA: Ports and shipping[br]b. 18 June 1791 Dumbarton, Scotlandd. 23 June 1876 Shandon, Dunbartonshire, Scotland[br]Scottish shipbuilder one of the greatest shipbuilders of all time, known as the "father" of Clyde shipbuilding.[br]Educated at Dumbarton Grammar School, Robert Napier had been destined for the Church but persuaded his father to let him serve an apprenticeship as a blacksmith under him. For a while he worked in Edinburgh, but then in 1815 he commenced business in Glasgow, the city that he served for the rest of his life. Initially his workshop was in Camlachie, but it was moved in 1836 to a riverside factory site at Lancefield in the heart of the City and again in 1841 to the Old Shipyard in the Burgh of Govan (then independent of the City of Glasgow). The business expanded through his preparedness to build steam machinery, beginning in 1823 with the engines for the paddle steamer Leven, still to be seen a few hundred metres from Napier's grave in Dumbarton. His name assured owners of quality, and business expanded after two key orders: one in 1836 for the Honourable East India Company; and the second two years later for the Royal Navy, hitherto the preserve of the Royal Dockyards and of the shipbuilders of south-east England. Napier's shipyard and engine shops, then known as Robert Napier and Sons, were to be awarded sixty Admiralty contracts in his lifetime, with a profound influence on ship and engine procurement for the Navy and on foreign governments, which for the first time placed substantial work in the United Kingdom.Having had problems with hull subcontractors and also with the installation of machinery in wooden hulls, in 1843 Napier ventured into shipbuilding with the paddle steamer Vanguard, which was built of iron. The following year the Royal Navy took delivery of the iron-hulled Jackall, enabling Napier to secure the contract for the Black Prince, Britain's second ironclad and sister ship to HMS Warrior now preserved at Portsmouth. With so much work in iron Napier instigated studies into metallurgy, and the published work of David Kirkaldy bears witness to his open-handedness in assisting the industry. This service to industry was even more apparent in 1866 when the company laid out the Skelmorlie Measured Mile on the Firth of Clyde for ship testing, a mile still in use by ships of all nations.The greatest legacy of Robert Napier was his training of young engineers, shipbuilders and naval architects. Almost every major Scottish shipyard, and some English too, was influenced by him and many of his early foremen left to set up rival establishments along the banks of the River Clyde. His close association with Samuel Cunard led to the setting up of the company now known as the Cunard Line. Napier designed and engined the first four ships, subcontracting the hulls of this historic quartet to other shipbuilders on the river. While he contributed only 2 per cent to the equity of the shipping line, they came back to him for many more vessels, including the magnificent paddle ship Persia, of 1855.It is an old tradition on the Clyde that the smokestacks of ships are made by the enginebuilders. The Cunard Line still uses red funnels with black bands, Napier's trademark, in honour of the engineer who set them going.[br]Principal Honours and DistinctionsKnight Commander of the Dannebrog (Denmark).
