A technical writer from the early 1900s, he is best known for a detailed practical guide to nitro-explosives and related materials. His work has remained accessible through major public-domain and library collections, which has helped preserve it for modern readers.

by P. Gerald (Percy Gerald) Sanford
Little biographical information about this author was easy to confirm from reliable public sources, so what survives most clearly is the work itself. He is listed in major library and public-domain catalogs as P. Gerald (Percy Gerald) Sanford, the author of Nitro-Explosives: A Practical Treatise.
That book was issued in the early 20th century and focuses on the properties, manufacture, and analysis of nitrated substances, including fulminates, smokeless powders, and celluloid. The surviving catalog records and digital editions suggest that his reputation rests on careful technical explanation rather than a large body of widely known books.
Today, Sanford is mainly remembered through archival and digitized editions preserved by projects such as Project Gutenberg, HathiTrust, and the Internet Archive. For readers interested in the history of chemistry, industry, or military technology, his writing offers a window into how explosive materials were understood and discussed in his era.
