Father Ferdinand Verbiest (1623-1688) was a Flemish Jesuit missionary in China during the Qing dynasty. He proved to the court of Kangxi Emperor that European astronomy was more accurate than Chinese astronomy. He then corrected the Chinese calendar and was later asked to rebuild and re-equip the Beijing Ancient Observatory, being given the role of Head of the Mathematical Board and Director of the Observatory. Verbiest was the only Westerner in Chinese history to ever receive the honour of a posthumous name by the Emperor. He is buried in Beijing.
