Nán Huáirén 南懷仁 / Ferdinand Verbiest, S.J. (1623–1688). Flemish Jesuit missionary, mathematician, astronomer, engineer, and diplomat; zì Dūnbó 敦伯 and Xūnqīng 勛卿. Born at Pittem in Flanders; entered the Society of Jesus 1641; sent to China 1659. Joined the Beijing Jesuit residence in 1660 as Adam Schall’s assistant. Imprisoned with Schall and others during the Yáng Guāngxiān 楊光先 anti-Christian persecution of 1664–1665; released and rehabilitated in 1669 when Kāngxī, then a young emperor, restored Western astronomy to the Imperial Astronomical Bureau (Qīntiānjiān). From 1669 served as Qīntiānjiān jiànzhèng (Director of the Imperial Astronomical Bureau), supervising the imperial calendar, the construction of the new Beijing observatory instruments (1669–1673; six bronze instruments still extant on the Beijing Ancient Observatory), the casting of cannon for the imperial armies, and Kāngxī’s mathematical-and-astronomical instruction. The most influential European at the Qīng court after Schall. Major Chinese-language works: Kūnyú túshuō 坤輿圖說 (KR2k0150, 1672) on world geography; Kūnyú quántú 坤輿全圖 (1674) — the great two-hemisphere imperial world map; Xīn zhì língtái yíxiàng zhì 新製靈臺儀象志 (1674) on the new observatory instruments; Kāngxī yǒngnián lìfǎ 康熙永年曆法 (a comprehensive astronomical/calendrical compendium); Yú yú lǐfǎ jiāshí (a calendrical treatise). Died at Beijing in Kāngxī 27 (1688) at age 65 and was given the imperial posthumous title Qínmǐn 勤敏. The catalog meta records him as “Xīyáng Nán Huáirén” — “Western-Sea Verbiest” — the formal Chinese designation.
