孙膑
Sun Tzu's historicity is uncertain. The Han dynasty historian Sima Qian and other traditional Chinese historians placed him as a minister to King Helü of Wu and dated his lifetime to 544–496 BC. Modern scholars accepting his historicity place the extant text of "The Art of War" in the later Warring States period based on its style of composition and its descriptions of warfare. Traditional accounts state that the general's descendant Sun Bin wrote a treatise on military tactics, also titled "The Art of War". Since Sun Wu and Sun Bin were referred to as Sun Tzu in classical Chinese texts, some historians believed them identical, prior to the rediscovery of Sun Bin's treatise in 1972.
