James Nicholas Douglass

Sir James Nicholas Douglass, (16 October 1826 – 19 June 1898) was an English civil engineer, a prolific lighthouse builder and designer, most famous for the design and construction of the fourth Eddystone Lighthouse, for which he was knighted.

Biography

James Nicholas Douglass was born in Bow, London, in 1826, the eldest son of Nicholas Douglass, also a civil engineer. After serving an apprenticeship with the Hunter and English company, he joined the engineering department of Trinity House, the United Kingdom's lighthouse authority.

Along with his brother William, James worked as an assistant to his father during the construction of James Walker's Bishop Rock Lighthouse in the Scilly Isles, earning the nickname 'Cap'n Jim' during the process.Palmer, M. ''Eddystone: the finger of light'', Seafarer, 2005, , p.103 After a brief period working for the Newcastle carriage builders R J & R Laycock, he returned in 1854 to assist in the lighthouse's final completion and to marry his fiancée Mary Tregarthen. Trinity House then engaged him as Resident Engineer to design the Smalls Lighthouse off the coast of Pembrokeshire, his first solo project.

Douglass based his plans on the proven design of John Smeaton for the third Eddystone lighthouse, which had used dovetailed granite blocks for strength.Trinity House – Smalls Lighthouse

The Smalls light was completed in 1861, at a cost of £50,125, and in a record-breaking time of two years.Charles, D. & Plisson, G. ''Lighthouses of Europe'', Watson-Guptill, 2001, , p.82 Douglass immediately went on to supervise the construction of the Wolf Rock Lighthouse, designed by James Walker, and was appointed as Engineer-in-Chief of Trinity House in 1862.

Douglass's design for the Smalls light was a great success and he went on to design some twenty lighthouses for Trinity House, including some wave-swept towers which remain major engineering achievements, such as the Longships Lighthouse off Land's End.Trinity House – Longships Lighthouse

The crowning achievement of James Douglass's career was the construction of the fourth Eddystone Lighthouse. Douglass was engaged to build a replacement for Smeaton's tower in 1877, and the new lighthouse was completed in 1882, the project being finished both without loss of life or serious injury and £18,745 under budget.Palmer, p.121 Douglass received a knighthood shortly afterwards for his services to engineering. He also carried out work on improving illumination using oil and gas burners and electricity.

In 1887 Douglass was elected a Fellow of the Royal Society. He retired in 1892, being succeeded as Engineer-in-Chief by Thomas Matthews, and died in 1898 at his home on the Isle of Wight. His youngest son Alfred also trained as a lighthouse engineer.Palmer, p.122 His eldest surviving son was William Tregarthen Douglass, who gained a considerable reputation as a civil engineer in the construction of lighthouses.

Controversy

Douglass was involved in a big public disputes with John Richardson Wigham. Wigham claimed that gas lights were superior to oil lamps, Douglass, then chief engineer to Trinity House, disagreed. In 1863 the Dublin Ballast Board funded Wigham's research and the new gas light was installed in the Baily Lighthouse, they then converted other lighthouses until Trinity House prohibited further conversion of lighthouses from oil to gas. After pressure from the Irish Parliamentary Party In 1871 trials were conducted at the two Happisburgh Lighthouses comparing oil with gas. Douglass reported that "the large gas burner was ex-focal and therefore that it was totally useless and wasted".

Douglass claimed that the design of "superposed lenses" at the Eddystone Lighthouse of 1882 were his. The same design "bi-form lens" was used by Wigham in the Galley Head lighthouse in 1877. There was a public dispute. Wigham had patented his design (Patent number 1015) in 1872. Wigham successfully sued Douglass for infringement of patent, and Douglass had to pay £2,500 to Wigham
