Carlos De Zafra
1882–1967
An engineer and military writer, he explored the science behind armor-piercing shells in a compact 1915 study that shows how quickly warfare technology was changing. His work is clear, practical, and especially interesting for listeners drawn to early modern engineering and military history.

About the author
Carlos de Zafra (1882–1967) is known for The Development of Armor-piercing Shells (With Suggestions for Their Improvement), a 1915 work on projectile design and military engineering. The book presents him as an M.E. and a faculty lecturer at New York University, suggesting a background that combined technical training with teaching.
Rather than writing for a general literary audience, he wrote as a specialist explaining how armor-piercing shells evolved and why their design mattered. That gives his work a direct, instructive tone: part history, part engineering discussion, and part window into the military thinking of the early twentieth century.
Reliable biographical details beyond those basics are limited in the sources I could confirm here, so it is safest to remember him chiefly as an engineer-author whose surviving reputation rests on this focused and historically revealing book.
