Sun Tzu
Sun Tzu (孫子 also commonly written in pinyin: Sūn Zǐ) was the author of The Art of War, an influential ancient Chinese book on military tactics. He is also one of the earliest realists in political science.Some scholars have concluded that the work was actually authored by unknown Chinese philosophers.
The only surviving source on the life of Sun Tzu is the biography written in the 2nd century BC by the historian Sima Qian, who describes him as a general who lived in the state of Wu in the 6th century BC. However, the biography is not consistent with other sources for the period, and both the form and content of the book indicate that it was most likely written between 400 BC and 320 BC.
