Frederick B. Maurice (1871–1951) British Army general and historian
Speaking in Carnegie Hall, New York City, on 4 April 1919.
Context: As a soldier who has spent a quarter of his life in the study of the science of arms, let me tell you I went into the British Army believing that if you want peace you must prepare for war. I believe now that if you prepare thoroughly and efficiently for war, you get war.
“In peace, prepare for war. In war, prepare for peace.”
Sun Tzu (-543–-495 BC) ancient Chinese military general, strategist and philosopher from the Zhou Dynasty
Sometimes erroneously prepended to the opening line "The art of war is of vital importance to the State", but appears to be a variation of the Roman motto "Si vis pacem, para bellum". It's not clear who first misattributed this phrase to Sun Tzu. The earliest appearance of the phrase in Google Books is 1920, when it appeared in a pharmaceutical journal, but no attribution was given then.
