Fèi Bóxióng 費伯雄 (1800–1879), zì Jìnqīng 晉卿, hào Yànyúnzǐ 硯雲子. Native of Wǔjìn 武進 (Chángzhōu, Jiāngsū). The founding figure of the Mènghé 孟河 medical lineage — the most prestigious 19th-century Chinese medical school, centred on the Mènghé (孟河) town in Wǔjìn county. Treated members of the imperial Dào-guāng-era court (he was twice summoned to Běijīng to treat the Dàoguāng emperor and an empress dowager) but declined formal office. His grandson Fèi Shēngfǔ 費繩甫 carried the Mènghé tradition into the Republican era. Principal works: Yī fāng lùn 醫方論 (KR3i041?), Yī chún shèng yì 醫醇賸義, Wàike biàn yì 外科辨疑, and the Shí jiàn běncǎo 食鑑本草 (KR3ec067) — a dietary materia medica focused on the pharmacology of foodstuffs, an important Mènghé contribution to the dietetic tradition. CBDB 85440 confirms the dates 1800–1878 (one-year variance against the conventional 1879 from his Mìnghé biography; the conventional figure is followed here for consistency with the Mènghé documentary tradition).
