author
Known for major tunnel engineering work as well as technical writing, this British civil engineer combined hands-on experience with a gift for explaining complex construction methods. He is best remembered in print for co-authoring a detailed 1922 book on shield and compressed-air tunneling.

by Bertram Henry Majendie Hewett, W. L. Brown
Bertram Henry Majendie Hewett was a British civil engineer whose career centered on tunneling and large construction works. Contemporary records summarized by Grace's Guide say he had long experience in this specialist branch of engineering, and that he later became engineer-in-charge of work connected with the Mersey Tunnel before being appointed its manager after the tunnel opened.
As an author, he is best known for Shield and Compressed Air Tunneling, published in 1922 with Sigvald Johannesson. The book reflects practical expertise in underground construction and helped document the methods, challenges, and engineering thinking behind shield tunneling in the early twentieth century.
Available sources on his personal life are quite limited, so it is safest to remember him chiefly through his professional work: an engineer closely associated with major tunneling projects and a writer whose technical book preserved that knowledge for later readers.
