1869–1952
A Marine Corps general with a writer’s eye for detail, he turned military knowledge into practical books for a wider audience. Best known as the author of Army and Navy Uniforms and Insignia, he paired firsthand service experience with a talent for clear explanation.
Born in Ohio in 1869, Dion Williams built a long career in the United States Marine Corps and rose to the rank of brigadier general. He graduated from the U.S. Naval Academy in 1891, later served in major campaigns of his era, and went on to become Assistant Commandant of the Marine Corps.
Alongside his military career, he wrote nonfiction that drew on his professional expertise. His best-known book, Army and Navy Uniforms and Insignia (1918), was designed to help readers identify ranks, corps, and branches of service across U.S. and foreign military forces.
Williams died in 1952. Today, he is remembered both as a significant Marine officer and as an author who made specialized military subjects more accessible to general readers.
