Lighthouse Construction and Illumination

Thomas Stevenson (1818-1887) was the son of the engineer Robert Stevenson, and father of the writer Robert Louis Stevenson. Like his brothers David and Alan, he became a lighthouse designer, being responsible for over thirty examples around Scotland. Throughout his career he was interested in the theory as well as the practice of his profession, and published over sixty articles on engineering and meteorology. He was an international expert on lighthouses, and advised on projects in India, China, Japan, New Zealand and Canada. Lighthouse Construction and Illumination, published in 1881, was an expanded version of his Lighthouse Illumination of 1859, and remained a standard text. Many of his improvements in illumination came into universal use. According to his son, as a result of Thomas' work 'the great sea lights in every quarter of the world now shine more brightly'.
