Sun Bin (c. 382 - 316 BC) was a Chinese general, military strategist, and writer who lived during the Warring States period of Chinese history. A supposed descendant of Sun Tzu, Sun was tutored in military strategy by the hermit Guiguzi. He was accused of treason while serving in the Wei state and was sentenced to face-tattooing (criminal branding) and had his kneecaps removed (trad. 臏, sim. 膑, pinyin: bìn), permanently crippling him. Sun escaped from Wei later and rose to prominence in the Qi state, by serving as a military strategist and commander. He led Qi to victory against the Wei state at the Battle of Guiling and Battle of Maling. Sun authored the military treatise Sun Bin's Art of War, which was rediscovered in a 1972 archaeological excavation after being lost for almost 2,000 years. Source: Wikipedia (en)
