Guilford L. (Guilford Lindsey) Molesworth

Born in 1828, he trained as an engineer at Putney and began work in Britain before taking on major responsibilities during the Crimean War at Woolwich. His career soon widened overseas, and he became deeply involved in railway and public-works projects in Ceylon and India, where he later served as Consulting Engineer for State Railways.

He was respected not only as a practicing engineer but also as a writer of technical reference books. His Pocket-Book of Useful Formulae and Memoranda for Civil and Mechanical Engineers became especially well known, valued for its practical, ready-to-use information.

Honored with a knighthood and remembered as a leading engineer of his era, he lived a remarkably long life, dying in 1925 at the age of ninety-six. His career offers a vivid picture of nineteenth-century engineering at a time when railways, industry, and imperial infrastructure were rapidly expanding.
