Bertram Henry Majendie Hewett

Bertram Henry Majendie Hewett was a civil engineer and technical writer whose best-known surviving book is Shield and Compressed Air Tunneling, published in 1922 with Sigvald Johannesson. The book focuses on the methods and challenges of tunnel construction, especially the use of shields and compressed air in difficult ground.

He is also listed by Project Gutenberg as a co-author, with W. L. Brown, of material published in Transactions of the American Society of Civil Engineers in 1910. Taken together, these records suggest that he was active in professional engineering circles and wrote for readers interested in the theory and practice of large infrastructure work.

Reliable biographical details about his personal life are limited in the sources I could confirm, so it is safest to remember him mainly through his engineering publications. Even so, those works still make him a useful figure for readers curious about the history of tunneling, construction methods, and the technical literature of the early 1900s.
