A lively early writer on technology and naval affairs, he helped everyday readers make sense of submarines, signaling, and other fast-changing military inventions at the turn of the 20th century. His best-known book explores undersea warfare just before submarines transformed modern conflict.

by Herbert C. Fyfe
Herbert C. Fyfe was a British writer active around the turn of the 20th century. The clearest details that can be confirmed from readily available sources are that he contributed articles to The Strand Magazine in 1899 and was later described on the title page of his best-known book as a "sometime Librarian of the Royal Institution, London."
His most notable work is Submarine Warfare, Past, Present, and Future (1902), a book written for general readers rather than specialists. In its preface, he explains that he wanted to make a complicated subject accessible without too much technical language, and that plainspoken approach still gives the book some charm today.
Besides submarines, Fyfe also wrote magazine pieces on subjects such as flying machines, X-rays in warfare, and military signaling. That mix suggests a writer drawn to new inventions and the ways science and technology were beginning to reshape war and everyday life.
