Ferdinand Verbiest, SJ (9 October 1623 – 28 January 1688) was a Flemish Jesuit missionary in China during the Qing dynasty. He was born in Pittem near Tielt in the County of Flanders (now part of Belgium). He is known as Nan Huairen (南懷仁) in Chinese. He was an accomplished mathematician and astronomer and proved to the court of the 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 roles of Head of the Mathematical Board and Director of the Observatory. He became close friends with the Kangxi Emperor, who frequently requested his instruction in geometry, philosophy and music. Verbiest worked as a diplomat, cartographer, and translator; he spoke Latin, German, Dutch, Spanish, Hebrew, Italian and Manchu. He wrote more than thirty books. During the 1670s, Verbiest designed what some claim to be the first ever self-propelled vehicle, in spite of its small size and the lack of evidence that it was actually built. He died in 1688.
