Kong Yingda (Chinese: 孔穎達; Wade–Giles: K'ung Ying-ta; 574 – 648), courtesy names Chongyuan (冲遠) and Zhongda (仲達), was a Chinese philosopher during the Sui and Tang dynasty. An ardent Confucianist, he is considered one of the most influential Confucian scholars in Chinese history. His most important work is the Wujing Zhengyi 五經正義 ("Correct Meaning of the Five Classics"), which became the standard curriculum for the imperial examinations, and the basis for all future official commentaries of the Five Classics. He was also "skilled at mathematics and the calendar." Source: Wikipedia (en)
