1779–1869
A self-taught strategist who moved from banking into the armies of Napoleon and later the Russian Empire, he became one of the 19th century’s most influential writers on war. His books helped turn battlefield experience into a clear, teachable system of military thought.

by baron de Antoine Henri Jomini
Born in Payerne, Switzerland, in 1779, Antoine-Henri Jomini built his reputation through a mix of military service and sharp analytical writing. He served in the French army during the Napoleonic era, later entered Russian service, and became widely known as a general, historian, and military theorist.
Jomini is especially remembered for his efforts to explain war through general principles that officers could study and apply. His writings on strategy and operations were enormously influential in the 19th century, and works such as The Art of War helped shape military education well beyond his own lifetime.
He died in Paris in 1869, but his name remains closely tied to the study of strategy. For many readers, Jomini stands at the meeting point of lived campaign experience and the attempt to make warfare understandable on the page.
