Fèi Shéngfǔ 費繩甫 (Fèi Yǔpéng 費禹彭; 1851–1914) — principal late-Qīng / early-Republican representative of the Ménghé 孟河 Fèi family, the most famous of the four great Ménghé medical lineages (Fèi, Mǎ, Cháo, Hé). He was the grandson of Fèi Bǎixióng 費伯雄 (1800–1879), whose Yīchún shèngyì 醫醇賸義 (1863) is the foundational mid-nineteenth-century statement of Ménghé clinical doctrine. Fèi Shéngfǔ moved to Shànghǎi in 1893 and became the principal Ménghé Fèi-family clinician of the foreign-concession period, alongside 丁甘仁 Dīng Gānrén (1865–1926) and Cáo Yǐngfǔ 曹穎甫 (1866–1937). His KR3ep050 Fèi Shéngfǔ xiānshēng yīàn 費繩甫先生醫案 was compiled by his disciples after his death and printed in the early Republican period. For modern treatment see Scheid 2007.
