author
A late-19th-century travel writer best known for a lively firsthand account of climbing Mont Blanc, he brings the mountain world to life with plain, energetic storytelling. His best-known book turns an alpine adventure into an approachable tale of effort, risk, and wonder.

by W. H. Le Mesurier
Very little biographical information about this author could be confirmed from the sources I found. He is clearly credited as W. H. Le Mesurier, and his known surviving work is An Impromptu Ascent of Mont Blanc, published in 1882.
That book is a firsthand travel narrative about an ascent of Mont Blanc. Its appeal lies in its direct, unvarnished style: instead of grand literary posing, it reads like a personal account of preparation, climbing, weather, hardship, and the excitement of reaching one of Europe's most famous peaks.
Because reliable source material about his life appears to be scarce, it is safest to remember him through this book itself — a compact example of Victorian adventure writing that still captures the fascination of alpine travel.
