1873–1968
Known for clear, practical books on explosives, this British chemist wrote reference works that were meant to be useful to professionals, not just specialists. His surviving publications suggest a writer deeply interested in the fast-changing science and industry of the early 20th century.

by Arthur Marshall
Arthur Marshall (1873–1968) was a chemist and technical writer whose best-known work is Dictionary of Explosives (1920). On that book’s title page, he is identified as A.C.G.I., F.I.C., and F.C.S., and as a Chemical Inspector in the Indian Ordnance Department.
The evidence available here points to a career closely tied to explosives science and ordnance work. In addition to Dictionary of Explosives, surviving digitized books attribute to him works such as A Short Account of Explosives and Explosives, Their History and Manufacture, Properties and Tests, showing that he wrote both compact introductions and more detailed technical studies.
Biographical details beyond his professional work are hard to confirm from the sources retrieved in this search, so it is safest to remember him as a specialist author: a chemist who helped organize complex information into books that engineers, inspectors, and other readers could actually use.
