§ 10. The Marquis of Worcester
Another aristocratic inventor, Edward Somerset, second marquis of Worcester, has received more credit than he deserved. He was interested in mechanics and employed a skilled mechanician, one Kaltoff, in his laboratory, but his claims to having invented a steam-engine do not bear critical investigation, and his well known Century of Inventions does not rise to the level of The Boy’s Own Book of the last century. Many of his suggestions, though ingenious, are based on fallacies, and comparatively few of them were practical.
