Qí Kūn 祁坤 (zì Guǎngshēng 廣生; hào Kuìān 愧菴, also Shēngyángzǐ 生陽子; fl. Shùnzhì – Kāngxī, 清), Yānyuè 燕越 (Héběi) native; Imperial Physician (御醫) of the Qīng Tàiyīyuàn under the early Kāngxī reign. Author of KR3ek011 Wàikē dà chéng 外科大成 (4 juǎn, Kāngxī 4 = 1665), the most ambitious early-Qīng surgical compendium. Through the mediation of his grandson Qí Hóngyuán 祁宏源 — who headed the surgical compilation team for the imperial Yīzōng jīnjiàn (1742, cf. KR3ek009) — Qí Kūn’s organisational scheme and a substantial portion of his prescriptions entered the official Qīng imperial-medical curriculum and shaped two centuries of imperial-medical-academy training. Lifedates are not securely documented; his grandson’s 1742 dates place Qí Kūn one generation earlier (born c. 1600–1620, died after 1665). Not in CBDB.
