‘Whenever I smell salt water, I know that I am not far from one of the works of my ancestors,’ wrote Robert Louis Stevenson in 1880. ‘When the lights come out at sundown along the shores of Scotland, I am proud to think they burn more brightly for the genius of my father!’
Robert Louis Stevenson was the most famous of the Stevensons, but not by any means the most productive. The Lighthouse Stevensons, all four generations of them, built every lighthouse round Scotland, were responsible for a slew of inventions in both construction and optics, and achieved feats of engineering in conditions that would be forbidding even today. The same driven energy which Robert Louis Stevenson put into writing, his ancestors put into lighting the darkness of the seas. The Lighthouse Stevensons is a story of high endeavour, beautifully told; indeed, this is one of the most celebrated works of historical biography in recent memory.
